Colon Cancer
  • Colon cancer is third most common cancer in the
    United States.
  • Colon cancer is cancer that starts in the large
    intestine or the rectum. Such cancer is sometimes
    referred to as "colorectal cancer."
  • There is no single cause for colon cancer. Nearly
    all colon cancers begin as non-cancerous (benign)
    polyps, which slowly develop into cancer.
  • Stage I and II colon cancer have very high cure
    rates (60 to 90) lower cure rates are seen
    with stage III and IV colon cancer.
  • To detect colon cancer early, when it is most
    curable, everyone over the age of 55 should have
    bi-annual endoscopic examinations of the colon.

6
Colon Cancer Risk Factors
  • You have a higher risk for colon cancer if you
    have
  • Cancer elsewhere in the body
  • Colorectal polyps (growth sticks out of lining of
    colon)
  • Crohns Disease (chronic inflammation of
    gastrointestinal tract)
  • Family history of colon cancer
  • Personal history of breast cancer
  • Diet low in fiber and high in fat

7
Colon Cancer Symptoms
  • Many cases of colon cancer have no symptoms. The
    following symptoms, however, may indicate colon
    cancer
  • Abdominal pain and tenderness in the lower
    abdomen
  • Blood in the stool
  • Diarrhea, constipation, or other change in bowel
    habits
  • Intestinal obstruction
  • Narrow stools
  • Unexplained anemia
  • Weight loss with no known reason

8
Types of Colon Cancer Examines
  • There are 4 basic tests for colon cancer..
  • 1 Stool test (to check for blood)
  • 2 Sigmoidoscopy (inspection of the lower colon)
  • 3 Colonoscopy (inspection of the entire colon)
  • 4 Double contrast barium enema
  • All 4 are effective in catching cancers in the
    early stages, when treatment is most beneficial.

9
Colonoscopy/Sigmoidoscopy
10
Barium Enema
  • The barium enema is a valuable diagnostic tool
    that helps detect abnormalities in the large
    intestine (colon).
  • The barium enema, along with colonoscopy, remain
    standards in the diagnosis of colon cancer and
    other diseases of the colon.

11
Barium Enema
12
Stages of Cancer
  • The staging of a carcinoma has to do with the
    size of the tumor, and the degree to which it has
    penetrated.
  • When the tumor is small and has not penetrated
    the mucosal layer, it is said to be stage I
    cancer.
  • Stage II tumors are into the muscle wall, and
    stage III involves nearby lymph nodes.
  • The rare stage IV cancer has spread
    (metastasized) to remote organs.

13
Stages of Cancer
14
Colon Culture
  • When polyps are discovered in a sigmoidoscopy (an
    inspection of the lower third of the large
    intestine), they are retrieved to be tested for
    cancer.
  • If a large amount of polyps are found, a more
    thorough examination of the entire length of the
    large intestine (a colonoscopy) may be
    recommended.

Colon Cancer Treatment
  • Surgery is main treatment for colon cancer and
    removal of the involved colon is required.
  • If cancer is located near rectum, a colostomy may
    be necessary.
  • Stage I and II colon cancer, surgery is usually
    the only treatment.
  • Stage III or IV colon cancer, chemotherapy is
    necessary after surgery.
  • Chemotherapy may also be helpful in some selected
    stage II patients.
  • Chemotherapy involves a course of drugs which are
    toxic to cancer cells.

22
Colostomy
  • A colostomy is done when the lower large
    intestine, rectum, or anus is unable to function
    normally. Intestinal obstruction with associated
    inflammation, is a common indication for
    colostomy.
  • A colostomy creates an opening on the abdomen
    for the drainage of stool from the large
    intestine.
  • The end of the healthy colon brought out to the
    skin of the abdominal wall, where it is sutured
    in place. An adhesive drainage bag is placed
    around the opening. The abdominal incision is
    then closed.
  • In more than 90 of the cases, the surgery is
    successful.

27
Lung Cancer
  • Lung cancer is cancer that begins in the lungs,
    the two organs found in the chest that help you
    breathe.
  • The lungs are made up of areas called lobes. The
    right lung has three lobes the left lung has
    two, so there's room for the heart. When you
    breathe, air goes through your nose, down your
    windpipe (trachea), and into the lungs where it
    spreads through tubes called bronchi. Most lung
    cancer begins in the cells that line these tubes.
  • Lung cancer is the deadliest type of cancer for
    both men and women. Each year, more people die of
    lung cancer than breast, colon, and prostate
    cancers combined.
  • Lung cancer is more common in older adults. It is
    rare in people under age 45.

28
Lung Cancer Causes
  • Cigarette smoking is the leading cause of lung
    cancer.
  • The more cigarettes you smoke per day and the
    earlier you started smoking, the greater your
    risk of lung cancer. There is no evidence that
    smoking low-tar cigarettes lowers the risk.
  • However, lung cancer has occurred in people who
    have never smoked.
  • Secondhand smoke (breathing the smoke of others)
    increases your risk of lung cancer. According to
    the American Cancer Society, an estimated 3,000
    non-smoking adults will die each year from lung
    cancer related to breathing secondhand smoke.

29
Lung Cancer Risk Factors
  • The following may also increase one's risk of
    lung cancer
  • High levels of air pollution
  • High levels of arsenic in drinking water
  • Radon gas
  • Asbestos
  • Family history of lung cancer
  • Radiation therapy to the lungs
  • Exposure to cancer-causing chemicals such as
    uranium, vinyl chloride, nickel chromates, coal
    products, mustard gas, gasoline, and diesel
    exhaust

30
Lung Cancer Symptoms
  • Early lung cancer may not cause any symptoms.
    Many times, lung cancer is found when an x-ray is
    done for another reason.
  • Symptoms depend on the specific type of cancer
    you have, but may include
  • Cough that doesn't go away
  • Coughing up blood
  • Shortness of breath
  • Wheezing
  • Chest Pain
  • Loss of appetite
  • Losing weight without trying
  • Fatigue

31
Lung Cancer Exams/Tests
  • The health care provider will perform a physical
    exam and ask questions about your medical
    history. You will be asked if you smoke, and if
    so, how long you have smoked.
  • When listening to the chest with a stethoscope,
    the health care provider can sometimes hear fluid
    around the lungs, which could (but doesn't
    always) suggest cancer.
  • Tests that may be performed include
  • Chest x-ray
  • Sputum cytology test
  • Blood work
  • CT scan of the chest
  • MRI of the chest

32
Sputum Cytology Test
  • A sputum sample is obtained by coughing deeply
    and expelling the material that comes from the
    lungs into a sterile cup. The sample is taken to
    a laboratory and placed in a medium under
    conditions that allow the organisms to grow. A
    positive culture may identify disease-producing
    organisms that may help diagnose bronchitis,
    tuberculosis, a lung abscess, or pneumonia.

33
Sputum Cytology Test
34
Removal of Lung Tissue
  • In some cases, the health care provider may need
    to remove a piece of tissue from your lungs for
    examination under a microscope. This is called a
    biopsy. There are several ways to do this
  • Bronchoospy combined with biopsy
  • Pleural biopsy
  • Mediastinoscopy with biopsy

35
Bronchoscopy
  • A bronchoscope is a tube with a tiny camera on
    the end which is inserted through the nose (or
    mouth) into the lungs. During a bronchoscopy
    procedure, a scope will be inserted through the
    nostril until it passes through the throat into
    the trachea and bronchi. A bronchoscope is used
    to provide a view of the airways of the lung. The
    scope also allows the doctor to collect lung
    secretions and lung tissue for biopsy for tissue
    specimens.

36
Bronchoscopy
37
Pleural Biopsy
  • In a pleural biopsy, a small piece of pleural
    tissue in the chest is removed with a needle. The
    biopsy may distinguish between a cancerous and
    noncancerous disease. It also can help to detect
    whether a viral, fungal or parasitic disease is
    present.

38
Pleural Biopsy
39
Mediastinoscopy
  • Mediastinoscopy is a procedure in which a lighted
    instrument (mediastinoscope) is inserted through
    a neck incision to visually examine the
    structures in the top of the chest cavity and
    take tissue samples. This procedure can be used
    to biopsy lymph nodes surrounding the airway to
    help diagnose or see how far a particular
    disease has spread.

41
Lung Cancer Treatment
  • Treatment depends on the specific type of lung
    cancer. Each type is treated differently.
    Chemotherapy, radiation, and surgery may be
    needed.
  • Small cell lung cancer spreads quickly throughout
    the body, treatment must include cancer-killing
    drugs (chemotherapy) taken by mouth or injected
    into the body. Chemotherapy may be combined with
    high-powered x-rays (radiation therapy).
  • Chemotherapy or radiation will be needed if
    surgery occurs. However, because the disease has
    usually spread by the time it is diagnosed, very
    few patients with small cell lung cancer are
    candidates for surgery.
  • Combination chemotherapy and radiation treatment
    is given to persons with extensive small cell
    lung cancer. However, the treatment only helps
    relieve symptoms it does not cure the disease.

42
Lung Cancer Treatment
  • There are different types of treatment for
    non-small cell lung cancer
  • Surgery - part or all of the lung is removed
  • Radiation therapy - uses powerful x-rays or other
    radiation to kill cancer cells
  • Chemotherapy - uses drugs to kill cancer cells
    and stop new ones from growing
  • Laser therapy - a small beam of light burns and
    kills cancer cells

43
Lung Cancer Prevention
  • If you smoke, quit. It is never too late to stop
    smoking. You should also avoid breathing in the
    smoke from other people's cigarettes, cigars, or
    pipes.
  • Eating a diet rich in fruits and vegetables may
    help prevent some cases of lung cancer.

45
Prostate Cancer
  • Prostate cancer is cancer that grows in prostate
    gland. The prostate is a small, walnut-sized
    structure that makes up part of a man's
    reproductive system. It wraps around the urethra,
    the tube that carries urine out of the body.
  • Prostate cancer is the third most common cause of
    death from cancer in men of all ages and is the
    most common cause of death from cancer in men
    over 75 years old. Prostate cancer is rarely
    found in men younger than 40.
  • Men at higher risk include African-America men
    older than 60, farmers, tire plant workers,
    painters, and men exposed to cadmium. The lowest
    number of cases occurs in Japanese men and those
    who do not eat meat (vegetarians).

46
Prostate Cancer Causes
  • The cause of prostate cancer is unknown, some
    studies have shown a relationship between high
    dietary fat intake and increased testosterone
    levels. When testosterone levels are lowered
    either by surgical removal of the testicles or by
    medication, prostate cancer can slowly get
    better.
  • There is no known association with benign
    prostatic hyperplasia (BPH).

47
Benign Prostatic Hyperplasia
48
Prostate Cancer Stages
  • Prostate cancers are grouped according to how
    quickly they spread and how different they are
    from the surrounding prostate tissue. This is
    called staging. There are several different ways
    to stage tumors, a common one being the A-B-C-D
    staging system, also known as the Whitmore-Jewett
    system
  • Stage A Tumor is not felt on physical
    examination, and is usually detected by accident
    after prostate surgery is done for other reasons.
  • Stage B Tumor is only in the prostate and
    usually detected during a physical exam or with a
    blood test.
  • Stage C Tumor has spread beyond the prostate but
    is not in the lymph nodes.
  • Stage D Tumor has spread (metastasized) to lymph
    nodes or other parts of the body, such as the
    bone and lungs.

49
Prostate Cancer Symptoms
  • With the advent of PSA (Prostate-specific
    antigen) testing, most prostate cancers are now
    found before they cause symptoms. Additionally,
    while most of the symptoms listed below can be
    associated with prostate cancer, they are more
    likely to be associated with non-cancerous
    conditions.
  • Urinary hesitancy (delayed or slowed start of
    urinary stream)
  • Urinary dribbling, especially immediately after
    urinating
  • Urinary retention
  • Pain with urination
  • Pain with ejaculation
  • Lower back pain
  • Pain with bowel movement

50
Prostate Cancer Exams/Tests
  • A rectal exam often reveals an enlarged prostate
    with a hard, irregular surface. A number of tests
    may be done to confirm the diagnosis of prostate
    cancer.
  • PSA test may be high, although non-cancerous
    enlargement of the prostate can also increase PSA
    levels.
  • Urinalysis may show blood in the urine.
  • Urine or prostatic fluid cytology may reveal
    unusual cells.
  • Prostate biopsy confirms the diagnosis.
  • A newer test called AMACR is more sensitive for
    determining the presence of prostate cancer than
    the PSA test.

51

52
Prostate Cancer Treatment
  • The appropriate treatment of prostate cancer is
    often controversial. Treatment options vary based
    on the stage of the tumor. In the early stages,
    surgery and radiation therapy may be used to
    remove or kill the tumor.
  • Prostate cancer that has spread may be treated
    with drugs to reduce testosterone levels, surgery
    to remove the testes, or chemotherapy.
  • Surgery, radiation therapy, and hormonal therapy
    can interfere with sexual desire or performance
    on either a temporary or permanent basis. Discuss
    your concerns with your health care provider.

53
Prostate Cancer Surgery
  • Surgery is usually only recommended after
    thorough evaluation and discussion of all
    treatment options. A man considering surgery
    should be aware of the benefits and risks of the
    procedure.
  • Removal of prostate gland (Radical Prostatectomy)
    is often recommended for treatment of stage A and
    B prostate cancers. This is a lengthy procedure,
    usually done using general or spinal anesthesia.
    An surgical cut is made through the abdomen or
    perineal area. You may remain in the hospital for
    5 to 7 days. Possible complications include
    impotence and urinary incontinence, although
    nerve-sparing procedures may reduce the risk of
    these complications. This surgery should be done
    by a urologist with extensive experience doing
    this specific procedure.

54
Radical Prostatectomy
55
Prostate Cancer Radiation
  • Radiation therapy used primarily to treat
    prostate cancers classified as stages A, B, or C.
    Patients whose health makes risk of surgery high,
    radiation therapy is often the preferred
    alternative. Radiation therapy to the prostate
    gland is either external or internal
  • External beam radiation therapy is done in a
    radiation oncology center by specially trained
    radiation oncologists, usually on an outpatient
    basis. Prior to treatment, a therapist will mark
    the part of the body that is to be treated with a
    special pen. The radiation is delivered to the
    prostate gland using a device that resembles a
    normal x-ray machine. The treatment itself is
    generally painless. Side effects may include loss
    of appetite, fatigue, skin reactions such as
    redness and irritation, rectal burning or injury,
    diarrhea, and blood in urine. External beam
    radiation therapy is usually done 5 days a week
    for 6 - 8 weeks.

56
Prostate Cancer Radiation
  • Internal radiation therapy places radioactive
    seeds inside you, directly in or near the tumor.
    A surgeon makes a small cut in the area to inject
    the seeds. They are so small, you don't feel
    them. The seeds can be temporary or permanent.
    Because internal radiation therapy is directed to
    the prostate, it reduces damage to the tissues
    surrounding the prostate. Side effects may
    include pain, swelling or bruising in your penis
    or scrotum, red-brown urine or semen, impotence,
    incontinence, and diarrhea.

57
Prostate Cancer Prevention
  • There is no known prevention. Following a
    vegetarian, low-fat diet or one similar to the
    traditional Japanese diet may lower risk. Early
    identification (as opposed to prevention) is now
    possible by yearly screening of men over 40 or 50
    years old through digital rectal examination
    (DRE) and PSA blood test.
  • There is a debate, however, as to whether PSA
    testing should be done in all men. There are
    several potential downsides to PSA testing. The
    first is that a high PSA does not always mean a
    patient has prostate cancer. The second is that
    health care providers are detecting and treating
    some very early-stage prostate cancers that may
    never have caused the patient any harm. The
    decision about whether to pursue a PSA should be
    based on a discussion between patient and health
    care provider.

59
Liver Cancer
  • Hepatocellular carcinoma is cancer of the liver.
  • This type of cancer occurs more often in men than
    women, usually in people 50 to 60 years old. The
    disease is more common in parts of Africa and
    Asia than in North or South America and Europe.

60
Liver Cancer Causes
  • The cause of liver cancer is usually cirrhosis
    (scarring of the liver).
  • Cirrhosis may be caused by viral hepatitis,
    primarily hepatitis B and C, alcohol abuse,
    autoimmune diseases of the liver, and other
    diseases that result in chronic inflammation of
    the liver.
  • The most common cause for cirrhosis in the United
    States is alcohol abuse.

61
Liver Cancer Symptoms
  • Abdominal pain or tenderness, particularly in the
    right-upper quadrant
  • Enlarged abdomen
  • Easy bruising or bleeding
  • Jaundice (a yellow discoloration of the skin and
    eyes)

62
Liver Cancer Exams/Tests
  • Physical examination shows an enlarged, tender
    liver.
  • A liver biopsy shows hepatocellular carcinoma.
  • There may be a mass shown on abdominal CT scan.
  • A liver scan may indicate an abnormality.
  • Liver enzymes (liver function tests) are
    elevated.

63
Liver Biopsy
64
Liver CT Scan
65
Liver Cancer Treatment
  • Aggressive surgery or liver transplantation may
    be successful in treating small or slow-growing
    tumors if they are diagnosed early.
  • Chemotherapy and radiation treatments are not
    usually effective but may be used to shrink large
    tumors so that surgery has a greater chance of
    success.

66
Liver Cancer Outlook
  • The usual outcome is poor, because only 10 - 20
    of hepatocellular carcinomas can be removed
    completely using surgery.
  • If the cancer cannot be completely removed, the
    disease is usually deadly within 3 to 6 months,
    although this varies greatly. Survival much
    longer than this occasionally occurs.

67
Liver Cancer Prevention
  • Preventing and treating viral hepatitis may help
    reduce risk.
  • Avoid excessive alcohol consumption.
  • Certain patients may benefit from hemochromatosis
    screening.

68
Kidney Cancer
  • Renal cell carcinoma is a type of kidney cancer
    in which the cancerous cells are found in the
    lining of very small tubes (tubules) in the
    kidney.
  • Renal cell carcinoma is the most common type of
    kidney cancer in adults. It occurs most often in
    people 50 - 70 years old, and typically affects
    men.
  • The exact cause is unknown.
  • Kidneys are responsible for removing wastes from
    the body, regulating electrolyte balance and
    blood pressure, and stimulating red blood cell
    production.

69
Kidney Cancer Causes
  • Dialysis treatment
  • Family history of the disease
  • Genetics
  • Smoking
  • Von Hippel-Lindau disease (a hereditary disease
    that affects the capillaries of the brain)

70
Dialysis
  • Dialysis is a method of removing toxic substances
    (impurities or wastes) from the blood when the
    kidneys are unable to do so.
  • Dialysis uses special ways of accessing the blood
    in the blood vessels.
  • Blood is diverted from the access point in the
    body to a dialysis machine. Here, the blood flows
    counter-current to a special solution called the
    dialysate. The chemical imbalances and impurities
    of the blood are corrected and the blood is then
    returned to the body. Typically, most patients
    undergo hemodialysis for three sessions every
    week. Each session lasts 3 - 4 hours.

71
Kidney Cancer Symptoms
  • Abdominal pain
  • Abnormal urine color (dark, rusty, or brown)
  • Back pain
  • Blood in urine
  • Emaciated, thin, malnourished appearance
  • Enlargement of one testicle
  • Flank pain (pain in one side of the body between
    the upper abdomen and the back
  • Swelling or enlargement of the abdomen
  • Unintentional weight loss of more than 5 of body
    weight

72
Kidney Cancer Exams/Tests
  • Palpation of the abdomen may show a mass or organ
    enlargement, particularly of the kidney or liver.
    Men may have a varicocele in the testicles.
  • Intravenous pyelogram (IVP) - iodine-based
    contrast dye is injected into a vein, a series of
    images are taken at timed intervals.
  • Kidney x-ray
  • Renal arteriography x-ray of the blood vessels
    in the kidney.
  • Ultrasound of the abdomen and kidney
  • Urine test

Varicocele
75
Kidney Cancer Treatment
  • Nephrectomy - surgical removal of all or part of
    the kidney is recommended. This may include
    removing the bladder or surrounding tissues or
    lymph nodes.
  • Radiation therapy does not usually work for renal
    cell carcinoma and, therefore, is not often used.
  • Many chemotherapy drugs and other medications
    have been successful in reducing the growth of
    some renal cell carcinomas, including cancers
    that have spread. Current therapies such as
    interferon and interleukin-2 work by blocking the
    blood supply of the tumor. Some chemotherapy
    drugs have been used to treat this and other
    cancers for many years.
  • A cure is unlikely unless all of the cancer is
    removed with surgery.

79
Kidney Cancer Outlook
  • The outcome depends on the degree of cancer
    spread.
  • The survival rate is highest if the tumor is in
    the early stages and has not spread outside the
    kidney.
  • If it has spread to the lymph nodes or to other
    organs, the survival rate is much lower.

80
Kidney Cancer Prevention
  • Stop smoking.
  • Follow your health care provider's
    recommendations in the treatment of kidney
    disorders, especially those that may require
    dialysis.

81
Pancreatic Cancer
  • Pancreatic carcinoma is cancer of the pancreas.
  • Pancreatic cancer is the fourth leading cause of
    death from cancer in the United States.
  • The disease is slightly more common in men than
    in women, and risk increases with age.

82
Pancreatic Cancer Causes
  • The cause is unknown, but it is more common in
    smokers and in obese individuals.
  • Almost a third of cases of pancreatic cancer are
    due to cigarette smoking.
  • There is controversy as to whether type 2
    diabetes is a risk factor for pancreatic cancer.
  • A small number of cases are known to be related
    to syndromes that are passed down through
    families.

83
Pancreatic Cancer Symptoms
  • Weight loss
  • Abdominal pain
  • Loss of appetite
  • Jaundice
  • Nausea and vomiting
  • Weakness
  • Fatigue
  • Diarrhea
  • Indigestion
  • Back pain
  • Clay-colored stools
  • Paleness
  • Depression

84
Pancreatic Cancer Exams/Tests
  • ERCP - procedure used to identify stones, tumors,
    or narrowing in the bile ducts. The procedure is
    done through an endoscope.
  • Abdominal CT scan
  • Pancreatic biopsy
  • Abdominal ultrasound
  • Abdominal MRI

85
ERCP
86
Pancreatic Cancer Treatment
  • At the time of diagnosis, only about 20 of
    pancreatic tumors can be removed by surgery. The
    standard procedure is called a pancreaticoduodenec
    tomy (Whipple procedure).
  • When the tumor is confined to the pancreas but
    cannot be removed, a combination of radiation
    therapy and chemotherapy may be recommended. When
    the tumor has spread (metastasized) to other
    organs such as the liver, chemotherapy alone is
    usually used.
  • For patients who have biliary obstruction
    (blockage of the vessels that transport bile) and
    the tumor cannot be totally removed, the
    obstruction must be relieved. There are generally
    two approaches to this -- surgery and placement
    of a biliary stent (similar to stents placed in
    the arteries of the heart to relieve blockages)
    during ERCP.

87
Pancreatic Cancer Outlook
  • Some patients with pancreatic cancer that is
    resectable (can be surgically removed) are cured.
    However, cure rates are significantly less than
    50.
  • Chemotherapy and radiation are often given after
    surgery to attempt to increase the cure rate. For
    pancreatic cancer that cannot be removed
    completely with surgery, or cancer that has
    spread beyond the pancreas, cure is not currently
    possible and the average survival is usually less
    than 1 year. Such patients might consider
    enrollment in a clinical trial (a medical
    research study to determine the best treatment).

88
Pancreatic Cancer Prevention
  • If you smoke, stop smoking.
  • Eat a diet high in fruits, vegetables, and whole
    grains.
  • Exercise regularly.

89
Oral Cancer
  • Oral cancer is cancer of the mouth.
  • Oral or mouth cancer most commonly involves the
    tissue of the lips or the tongue.
  • It may also occur on the floor of the mouth,
    cheek lining, gingiva (gums), or palate (roof of
    the mouth).
  • Most oral cancers look very similar under the
    microscope and are called squamous cell
    carcinomas. These are malignant and tend to
    spread rapidly.
  • Oral cancer accounts for about 8 of all
    malignant growths.
  • Men get oral cancer twice as often as women,
    particularly men older than 40.

90
Oral Cancer Causes and Risks
  • Smoking and other tobacco use are associated with
    70-80 of oral cancer cases.
  • Smoke and heat from cigarettes, cigars, and pipes
    irritate the mucous membranes of the mouth.
  • Use of chewing tobacco or snuff causes irritation
    from direct contact with the mucous membranes.
  • Heavy alcohol use is another high-risk activity
    associated with oral cancer.
  • Other risks include poor dental and oral hygiene
    and chronic irritation (such as that from rough
    teeth, dentures, or fillings).
  • Some oral cancers begin as leukoplakia or mouth
    ulcers.

91
Oral Cancer Symptoms
  • Skin lesion, lump, or ulcer
  • May be a deep, hard edged crack in the tissue
  • Most often pale colored, may be dark or
    discolored
  • On the tongue, lip, or other mouth area
  • Usually painless at first (may develop a burning
    sensation or pain when the tumor is advanced)
  • Usually small
  • Additional symptoms
  • Abnormal taste in the mouth
  • Mouth sores
  • Swallowing difficulty
  • Tongue problems

92
Mouth Sores
93
Black Hairy Tongue
94
Oral Cancer Exams/Tests
  • An examination of the mouth by the health care
    provider or dentist shows a visible or palpable
    (can be felt) lesion of the lip, tongue, or other
    mouth area. As the tumor enlarges, it may become
    an ulcer and bleed. Speech difficulties, chewing
    problems, or swallowing difficulties may develop,
    particularly if the cancer is on the tongue.
  • A tongue biopsy, gum biopsy, and microscopic
    examination of the lesion confirm the diagnosis
    of oral cancer.

95
Oral Cancer Treatment
  • Surgical excision (removal) of the tumor is
    usually recommended if the tumor is small enough.
  • Radiation therapy and chemotherapy would likely
    be used when the tumor is larger or has spread to
    lymph nodes in the neck.
  • Surgery may be necessary for large tumors.
  • Rehabilitation may include speech therapy or
    other therapy to improve movement, chewing,
    swallowing, and speech.

96
Oral Cancer Outlook
  • Approximately 50 of people with oral cancer will
    live more than 5 years after diagnosis and
    treatment.
  • If the cancer is detected early, before it has
    spread to other tissues, the cure rate is nearly
    75.
  • Unfortunately, more than 50 of oral cancers are
    advanced at the time the cancer is detected. Most
    have spread to the throat or neck.
  • Approximately 25 of people with oral cancer die
    because of delayed diagnosis and treatment.

97
Oral Cancer Prevention
  • You should have the soft tissue of the mouth
    examined once a year. Many oral cancers are
    discovered by routine dental examination.
  • Other tips
  • Have dental problems corrected
  • Minimize or avoid alcohol use
  • Minimize or avoid smoking or other tobacco use
  • Practice good oral hygiene

Overview
  • Test
  • Videos Herpes, HPV, Lyme Disease, MRSA, Stroke,
    Diabetes, CVD

101
Lyme Disease
  • Lyme disease is an inflammatory disease spread
    through a tick bite.
  • Lyme disease was first reported in the United
    States in the town of Old Lyme, Connecticut, in
    1975. Cases have now been reported in most parts
    of the US. Most occur in the Northeast, upper
    Midwest, and along the Pacific coast. Lyme
    disease is usually seen during the late spring,
    summer, and early fall.
  • There are three stages of Lyme disease.
  • Stage 1 is called primary Lyme disease.
  • Stage 2 is called secondary Lyme disease.
  • Stage 3 is called tertiary Lyme disease.

102
Deer Tick
103
Lyme Diseases Causes and Risks
  • Lyme disease is caused by the bacteria Borrelia
    burgdorferi (B. burgdorferi). Certain ticks carry
    the bacteria. The ticks pick up the bacteria when
    they bite mice or deer that are infected with
    Lyme disease. You can get the disease if you are
    bitten by an infected tick.
  • Risk factors for Lyme disease include the
    following
  • Walking in high grasses
  • Doing activities that increase tick exposure
  • Having a pet that may carry ticks home

104
Lyme Disease Symptoms Initial Stage
  • Not everyone infected with the bacteria gets ill.
    If a person does become ill, the first symptoms
    resemble the flu and include
  • Chills
  • Fever
  • Headache
  • Lethargy
  • Muscle pain
  • There may be a "bulls-eye" rash, a flat or
    slightly raised red spot at the site of the tick
    bite often with a clear area in the center. It
    can be larger than 1 - 3 inches wide.

105
Bulls-Eye Rash
106
Lyme Disease Symptom Later Stages
  • Symptoms in people with the later stages of the
    disease include
  • Body-wide itching
  • Joint inflammation
  • Stiff neck
  • Unusual or strange behavior
  • Note Deer ticks can be so small that they are
    almost impossible to see. Therefore, many people
    with Lyme disease never even saw a tick.

107
Lyme Disease Exams/Tests
  • A blood test can be done to check for antibodies
    to the bacteria that causes Lyme disease. The
    most common one used is the ELISA for Lyme
    disease test (presence of Lyme disease antibodies
    in your blood ). A western blot test is done to
    confirm ELISA results.
  • A physical exam may show joint, heart, or brain
    problems in people with advanced Lyme disease.

108
Lyme Disease Treatment
  • Most people who are bitten by a tick do NOT get
    Lyme disease. Antibiotics may be offered to
    someone who isn't sick if
  • They have a tick that can carry Lyme disease
    attached to their body
  • The tick is estimated to have been attached to
    them for at least 36 hours
  • They are over 8 years old and are not pregnant or
    breastfeeding
  • Antibiotics are used to treat Lyme disease. The
    specific antibiotic used depends on the stage of
    the disease and the symptoms.
  • Anti-inflammatory medications, such as ibuprofen,
    are sometimes prescribed to relieve joint
    stiffness.

109
Lyme Disease Outlook
  • If diagnosed in the early stages, Lyme disease
    can be cured with antibiotics. Without treatment,
    complications involving joints, the heart, and
    the nervous system can occur.
  • Rarely, a person will continue having symptoms
    that can interfere with daily life. Some people
    call this post-Lyme disease syndrome.
    Unfortunately, there is no effective treatment
    yet for this syndrome.

110
Lyme Disease Complications
  • Advanced stages of Lyme disease can cause
    long-term joint inflammation (Lyme arthritis) and
    heart rhythm problems. Neurological problems are
    also possible, and may include
  • Decreased concentration
  • Memory disorders
  • Nerve damage
  • Numbness
  • Pain
  • Paralysis of the facial muscles
  • Sleep disorders
  • Visual disturbances

111
Lyme Disease Prevention
  • When walking or hiking in wooded or grassy areas
  • Spray all exposed skin and your clothing with
    insect repellant (spray outdoors only, do not use
    on face, use just enough to cover all other
    exposed skin, don't spray under clothing, don't
    apply over wounds or irritated skin, wash skin
    after going inside)
  • Wear light-colored clothing to make it easier to
    spot ticks
  • Wear long-sleeved shirts and long pants with the
    cuffs tucked into shoes or socks
  • Wear high boots, preferably rubber
  • Check yourself and your pets frequently during
    and after your walk or hike.
  • Ticks that carry Lyme disease are so small that
    they are very hard to see. After returning home,
    remove your clothes and thoroughly inspect all
    skin surface areas, including your scalp.

113
Staph Infections
  • Staph infections are caused by the bacteria
    Staphylococcus aureus, which many healthy people
    carry on their skin and in their noses without
    getting sick. But when skin is punctured or
    broken, staph bacteria can enter the wound and
    cause infections, which can lead to other health
    problems.

114
Staph Infection Causes
  • Staph bacteria can spread through the the
    following
  • Air
  • Contaminated surfaces
  • Person to person
  • Kids can carry staph bacteria from one area of
    their body to another  or pass it to other
    people via dirty hands or fingernails

115
Staph Infection Symptoms
  • Swollen lump or mass under the skin. (size of a
    pea or as large as a golf ball)
  • Skin red and irritated and might hurt when you
    touch it.
  • Grows very fast
  • White or yellow center
  • Weep, ooze, or crust
  • Spread to other skin areas

116
Staph Infection Prevention
  • You can help prevent staph infections by
    encouraging the following
  • Regular hand washing
  • Daily bathing
  • Keeping areas that have been cut clean or covered

117
Staph Infection Exams/Tests
  • Your doctor will look at your skin.
  • The diagnosis is primarily based on what the skin
    looks like.
  • A skin biopsy may be done to help make the
    diagnosis or determine the exact type of bacteria
    involved.

118
Staph Infection Treatment
  • Most localized staph skin infections can be
    treated by washing the skin with an antibacterial
    cleanser, warm soaks, applying an antibiotic
    ointment prescribed by a doctor, and covering the
    skin with a clean dressing.
  • To keep the infection from spreading, use a towel
    only once when you soak or clean an area of
    infected skin, then wash it.
  • Your doctor may prescribe an oral antibiotic for
    your staph skin infection. If so, take antibiotic
    on schedule for as many days as the doctor
    directs.
  • More serious staph infections may require
    hospitalization.

119
Staph Infection Outlook
  • Staph infections may heal on their own. Others
    usually respond well to treatment. However, a
    staph infection can return again and again for
    months or years following the first infection.

120
MRSA
  • Methicillin-resistant Staphylococcus aureus
    (MRSA), a type of staph bacteria with a
    resistance to the antibiotics usually used to
    treat staph infections. Although MRSA infections
    can be harder to treat, in most cases they heal
    with proper care.
  • MRSA can be fatal.
  • Most MRSA infections occur in hospitals or other
    health care settings, such as nursing homes and
    dialysis centers.

121
MRSA Symptoms
  • MRSA, generally start as small red bumps that
    resemble pimples, boils or spider bites.
  • These can quickly turn into deep, painful
    abscesses that require surgical draining.
    Sometimes the bacteria remain confined to the
    skin.
  • But they can also penetrate into the body,
    causing potentially life-threatening infections
    in bones, joints, surgical wounds, the
    bloodstream, heart valves and lungs.

MRSA Causes
  • Staph infections Staph bacteria are normally
    found on the skin or in the nose of about
    one-third of the population. If you have staph on
    your skin or in your nose but aren't sick, you
    are said to be "colonized" but not infected.
    Healthy people can be colonized and have no ill
    effects. However, they can pass the germ to
    others.
  • Staph bacteria are generally harmless unless they
    enter the body through a cut or other wound, and
    even then they often cause only minor skin
    problems in healthy people.
  • Past several years, serious infections have been
    occurring in otherwise healthy people in the
    community, for example athletes who share
    equipment or personal items.

126
MRSA Causes
  • Antibiotic resistanceSurvival tactics of
    bacteria contribute to antibiotic resistance,
    humans bear most of the responsibility for the
    problem. Leading causes of antibiotic resistance
    include
  • Unnecessary antibiotic use. Like other superbugs,
    MRSA is the result of decades of excessive and
    unnecessary antibiotic use. For years,
    antibiotics have been prescribed for colds, flu
    and other viral infections that don't respond to
    these drugs, as well as for simple bacterial
    infections that normally clear on their own.
  • Antibiotics in food and water. Prescription drugs
    aren't the only source of antibiotics. In the
    United States, antibiotics can be found in
    livestock. These antibiotics find their way into
    municipal water systems when the runoff from
    feedlots contaminates streams and groundwater.
  • Germ mutation. Even when antibiotics are used
    appropriately, they contribute to the rise of
    drug-resistant bacteria because they don't
    destroy every germ they target. Bacteria live on
    an evolutionary fast track, so germs that survive
    treatment with one antibiotic soon learn to
    resist others.

127
MRSA Risk Factors
  • Young age. Children susceptible because their
    immune systems aren't fully developed or they
    don't yet have antibodies to common germs.
  • Participating in contact sports. MRSA has
    affected sports teams. The bacteria spread easily
    through cuts and abrasions and skin-to-skin
    contact.
  • Sharing towels or athletic equipment. MRSA has
    spread among athletes sharing razors, towels,
    uniforms or equipment.
  • Having a weakened immune system. People with
    weakened immune systems, such as those living
    with HIV/AIDS, are more likely to have severe
    CA-MRSA infections.
  • Living in crowded or unsanitary conditions.
    Outbreaks of MRSA have occurred in military
    training camps and in American and European
    prisons.
  • Association with health care workers. People who
    are in close contact with health care workers are
    at increased risk of serious staph infections.

128
MRSA Treatment
  • MRSA still responds to certain medications. In
    hospitals and care facilities, doctors often rely
    on the antibiotic vancomycin to treat resistant
    germs.
  • MRSA may be treated with vancomycin or other
    antibiotics that have proved effective against
    particular strains.
  • Although vancomycin saves lives, it may become
    less effective as well. Some hospitals are
    already seeing strains of MRSA that are less
    easily killed by vancomycin.
  • In some cases, antibiotics may not be necessary.
    For example, doctors may drain a superficial
    abscess caused by MRSA rather than treat the
    infection with drugs.

129
MRSA Prevention
  • Wash your hands
  • Keep personal items personal
  • Keep wounds covered
  • Shower after athletic games or practices
  • Sit out athletic games or practices if you have a
    concerning infection
  • Sanitize linens
  • Get tested
  • Use antibiotics appropriately

131
Stroke
  • A stroke is an interruption of the blood supply
    to any part of the brain.
  • A stroke is sometimes called a "brain attack."
  • Every 45 seconds, someone in the United States
    has a stroke.
  • If blood flow is stopped for longer than a few
    seconds, the brain cannot get blood and oxygen.
    Brain cells can die, causing permanent damage.

132
Stroke Causes
  • A blood vessel carrying blood to the brain is
    blocked by a blood clot. This is called an
    ischemic stroke.
  • A blood vessel breaks open, causing blood to leak
    into the brain. This is a hemorrhagic stroke.
  • ISCHEMIC STROKE Most common type of stroke.
    Results from clogged arteries, a condition called
    atherosclerosis. Fatty deposits collect on the
    wall of the arteries, forming a sticky substance
    called plaque. Over time, the plaque builds up.
    Often, the plaque causes the blood to flow
    abnormally, which can cause the blood to clot.
  • HEMORRHAGIC STROKE Second major cause of stroke
    is bleeding in the brain. This can occur when
    small blood vessels in the brain become weak and
    burst. Some people have defects in the blood
    vessels of the brain that make this more likely.
    The flow of blood after the blood vessel ruptures
    damages brain cells.

133
Stroke
134
Stroke Risks
  • High blood pressure is the number one reason that
    you might have a stroke.
  • The risk of stroke is also increased by age,
    family history of stroke, smoking, diabetes, high
    cholesterol, and heart disease.
  • Certain medications increase the chances of clot
    formation, and therefore your chances for a
    stroke. Birth control pills can cause blood
    clots, especially in woman who smoke and who are
    older than 35.
  • Men have more strokes than women. But, women have
    a risk of stroke during pregnancy and the weeks
    immediately after pregnancy.
  • Cocaine use, alcohol abuse, head injury, and
    bleeding disorders increase the risk of bleeding
    into the brain.

135
Stroke Symptoms
  • The symptoms of stroke depend on what part of the
    brain is damaged. In some cases, a person may not
    even be aware that he or she has had a stroke.
  • Usually, a SUDDEN development of one or more of
    the following indicates a stroke
  • Weakness or paralysis of an arm, leg, side of the
    face, or any part of the body
  • Numbness, tingling, decreased sensation
  • Vision changes
  • Slurred speech, inability to speak or understand
    speech, difficulty reading or writing
  • Swallowing difficulties or drooling
  • Loss of memory
  • Vertigo (spinning sensation)
  • Loss of balance or coordination

136
Stroke Exams/Tests
  • During the exam, your doctor will look for
    specific neurologic, motor, and sensory deficits.
  • Tests are performed to determine the type,
    location, and cause of the stroke and to rule out
    other disorders that may be responsible for the
    symptoms. These tests include
  • Head CT or Head MRI -- used to determine if the
    stroke was caused by bleeding (hemorrhage) or
    other lesions and to define the location and
    extent of the stroke.
  • ECG (electrocardiogram) -- used to diagnose
    underlying heart disorders.
  • Echocardiogram -- used if the cause may be a
    blood clot from the heart, uses sound waves makes
    more detailed picture than an x-ray.

137
Stroke Treatment
  • Treatment varies, depending on the severity and
    cause of the stroke. Virtually all strokes,
    hospitalization is required, including intensive
    care and life support.
  • IMMEDIATE TREATMENT
  • Thrombolytic medicine, breaks up blood clots and
    can restore blood flow to the damaged area.
    Strict criteria for who can receive
    thrombolytics. The most important is that the
    person be examined and treated by a specialized
    stroke team within 3 hours of when the symptoms
    start. If the stroke is caused by bleeding rather
    than clotting, this treatment can make the damage
    worse -- so care is needed to diagnose the cause
    before giving treatment.
  • In other circumstances, blood thinners such as
    heparin and Coumadin are used to treat strokes.
    Aspirin may also be used.

138
Stroke Treatment
  • For hemorrhagic stroke, surgery is often required
    to remove pooled blood from the brain and to
    repair damaged blood vessels.
  • LONG-TERM TREATMENT
  • The goal of long-term treatment is to recover as
    much function as possible and prevent future
    strokes. Depending on the symptoms,
    rehabilitation includes speech therapy,
    occupational therapy, and physical therapy. The
    recovery time differs from person to person.
  • Certain therapies, such as repositioning and
    range-of-motion exercises, are intended to
    prevent complications related to stroke, like
    infections and bed sores. People should stay
    active within their physical limitations.
    Sometimes, urinary catheterization or
    bladder/bowel control programs may be needed to
    control incontinence.

139
Stroke Outlook
  • The long-term outcome from a stroke depends on
    the extent of damage to the brain, the presence
    of any associated medical problems, and the
    likelihood of recurring strokes.
  • Of those who survive a stroke, many have
    long-term disabilities, but about 10 of those
    who have had a stroke recover most or all
    function.
  • Fifty percent are able to be at home with medical
    assistance while 40 become residents of a
    long-term care facility like a nursing home.

140
Stroke Prevention
  • Get screened for high blood pressure at least
    every 2 years, especially if you have a family
    history of high blood pressure.
  • Have your cholesterol checked. If you are high
    risk, your LDL "bad" cholesterol should be lower
    than 70 mg/dL.
  • Follow a low-fat diet.
  • Quit smoking.
  • Exercise regularly -- 30 minutes a day if you are
    not overweight 60 - 90 minutes a day if you are
    overweight.
  • Do not drink more than 1 to 2 alcoholic drinks a
    day.

142
Diabetes
  • Diabetes is a life-long disease marked by high
    levels of sugar in the blood.
  • Diabetes affects more than 20 million Americans.
    About 54 million Americans have pre-diabetes.
  • To understand diabetes, it is important to first
    understand the normal process of food metabolism.
    Several things happen when food is digested
  • A sugar called glucose enters the bloodstream.
    Glucose is a source of fuel for the body.
  • An organ called the pancreas makes insulin. The
    role of insulin is to move glucose from the
    bloodstream into muscle, fat, and liver cells,
    where it can be used as fuel.
  • People with diabetes have high blood sugar. This
    is because their pancreas does not make enough
    insulin or their muscle, fat, and liver cells do
    not respond to insulin normally, or both.

143
Diabetes Causes/Risks
  • Diabetes can be caused by too little insulin (a
    hormone produced by the pancreas to control blood
    sugar), resistance to insulin, or both.
  • A parent, brother, or sister with diabetes
  • Obesity
  • Age greater than 45 years
  • Some ethnic groups (particularly African
    Americans, Native Americans, Asians, Pacific
    Islanders, and Hispanic Americans)
  • Gestational diabetes or delivering a baby
    weighing more than 9 pounds
  • High blood pressure
  • High blood levels of triglycerides (a type of fat
    molecule)
  • High blood cholesterol level
  • Not getting enough exercise

144
Diabetes Types
  • Type 1 diabetes is usually diagnosed in
    childhood. The body makes little or no insulin,
    and daily injections of insulin are needed to
    sustain life.
  • Type 2 diabetes is far more common than type 1
    and makes up most of all cases of diabetes. It
    usually occurs in adulthood. The pancreas does
    not make enough insulin to keep blood glucose
    levels normal, often because the body does not
    respond well to the insulin. Many people with
    type 2 diabetes do not know they have it,
    although it is a serious condition. Type 2
    diabetes is becoming more common due to the
    growing number of older Americans, increasing
    obesity, and failure to exercise.
  • Gestational diabetes is high blood glucose that
    develops at any time during pregnancy in a woman
    who does not have diabetes.

145
Diabetes Symptoms Type 1
  • Increased thirst
  • Increased urination
  • Weight loss in spite of increased appetite
  • Fatigue
  • Nausea
  • Vomiting
  • Patients with type 1 diabetes usually develop
    symptoms over a short period of time, and the
    condition is often diagnosed in an emergency
    setting

146
Diabetes Symptoms Type 2
  • Increased thirst
  • Increased urination
  • Increased appetite
  • Fatigue
  • Blurred vision
  • Slow-healing infections
  • Impotence in men

147
Diabetes Exams/Tests
  • Fasting blood glucose level
  • Random (non-fasting) blood glucose level (This
    test must be confirmed with a fasting blood
    glucose test.)
  • Oral glucose tolerance test (This test is used
    more for type 2 diabetes.)

148
Diabetes Treatment
  • There is no cure for diabetes. Treatment involves
    medicines, diet, and exercise to control blood
    sugar and prevent symptoms and complications.
  • Basic diabetes management skills will help
    prevent the need for emergency care. These skills
    include
  • How to recognize and treat low blood sugar
    (hypoglycemia) and high blood sugar
    (hyperglycemia)
  • What to eat and when
  • How to take insulin or oral medication
  • How to test and record blood glucose
  • How to adjust insulin or food intake when
    changing exercise and eating habits
  • How to handle sick days
  • Where to buy diabetes supplies and how to store
    them

149
Diabetes Outlook
  • With good blood glucose and blood pressure
    control, many of the complications of diabetes
    can be prevented.
  • Studies have shown that strict control of blood
    sugar and blood pressure levels in persons with
    diabetes helps reduce the risk of kidney disease,
    eye disease, nervous system disease, heart
    attack, and stroke.

Diabetes Prevention
  • Maintaining an ideal body weight and an active
    lifestyle may prevent the onset of type 2
    diabetes.
  • Currently there is no way to prevent type 1
    diabetes.

CVD
  • Cardiovascular disease is a broad term used to
    describe a range of diseases that affect your
    heart or blood vessels.
  • Various diseases fall under cardiovascular
    disease
  • Coronary artery disease
  • Heart attack
  • Heart failure
  • High blood pressure
  • The term "cardiovascular disease" is often used
    interchangeably with heart disease because both
    terms refer to diseases of the heart or arteries.
  • Cardiovascular disease is the No. 1 worldwide
    killer of men and women, including in the United
    States. For example, cardiovascular disease is
    responsible for 40 percent of all the deaths in
    the United States, more than all forms of cancer
    combined.

CVD Causes
  • Atherosclerosis is a disease that affects your
    arteries. Arteries are blood vessels that carry
    oxygen and nutrients from your heart to the rest
    of your body. Healthy arteries are flexible,
    strong and elastic.
  • Over time, too much pressure in your arteries can
    make the walls thick and stiff sometimes
    restricting blood flow to your organs and
    tissues. This process is called arteriosclerosis,
    or hardening of the arteries, and atherosclerosis
    is the most common form of this disorder. So if
    atherosclerosis is the most common cause of
    cardiovascular disease, you may wonder what
    ultimately causes atherosclerosis.
  • Some forms of cardiovascular disease aren't
    caused by atherosclerosis. Those forms include
    diseases such as congenital heart disease, heart
    valve diseases, heart infections or disease of
    the heart muscle called cardiomyopathy.

154
CVD Causes
  • The culprits are the same risk factors you've
    heard mentioned in connection with heart disease
    and cardiovascular disease
  • An unhealthy diet (lots of saturated fats)
  • Lack of exercise
  • Overweight
  • Smoking
  • All of these are major risk factors for
    developing atherosclerosis and, in turn,
    cardiovascular disease.

CVD Types
  • Coronary artery disease are diseases of the
    arteries that supply the heart muscle with blood.
    Means blood flow through coronary arteries has
    become obstructed, reducing blood flow to the
    heart muscle. Coronary artery disease and the
    resulting reduced blood flow to the heart muscle
    can lead to other heart problems, such as chest
    pain and heart attack.
  • Heart attack is an injury to the heart muscle
    caused by a loss of blood supply. Heart attack
    usually occurs when a blood clot blocks the flow
    of blood through a coronary artery a blood
    vessel that feeds blood to a part of the heart
    muscle. Interrupted blood flow to your heart can
    damage or destroy a part of the heart muscle.

157
CVD Types
  • Cardiomyopathy means diseases of the heart
    muscle. Some is genetic, some unknown.
    Cardiomyopathy means one of three things loss of
    heart muscle, heart chambers are enlarged and
    hypertrophic, which means the heart muscle is
    thickened.
  • Aneurysm is a bulge or weakness in a blood vessel
    (artery or vein) wall. Aneurysms usually get
    bigger over time. Because of that, they have the
    potential to rupture and cause life-threatening
    bleeding. Aneurysms can occur in arteries in any
    location in your body. The most common sites
    include the abdominal aorta and the arteries at
    the base of the brain.

CVD Types
  • High blood pressure (hypertension) is the
    excessive force of blood pumping through yo
