Sun Safety Skin Cancer Prevention
2
Vocabulary
  • Basal Cell Carcinoma type of cancer that forms
    in the basal cells (small cells found in the base
    of the outer skin layer)
  • Melanocyte cells in the skin and eyes that make
    and contain pigment called melanin
  • Melanoma form of cancer that forms in
    melanocytes
  • Squamous Cell Carcinoma cancer that forms in
    squamous cells (cells that make up the surface of
    the skin)

3
Vocabulary
  • Tumor an abnormal mass of tissue that results
    from excessive cell division. Have no useful
    purpose.
  • Benign Not cancerous does not invade nearby
    tissue or spread to other parts of the body
  • Malignant Cancerous a growth with a tendency
    to invade and destroy nearby tissue and spread to
    other parts of the body

4
Vocabulary
  • Stage the extent to which cancer has spread
    through the body.
  • Metastasis the spread of cancer from one part
    of the body to another
  • Ulceration a break on the skin or the surface
    of an organ, forms when the cells die or are cast
    off. Can be caused by cancer.

5
Vocabulary
  • Risk Factor anything that increases a persons
    chance of developing a disease (substance, agent,
    genetic alteration, trait, habit, or condition)
  • Ultraviolet Radiation (UV ) invisible rays that
    are a part of the energy that comes from the sun,
    tanning lamps, and tanning beds.
  • UVA radiation linked with skin damage that can
    lead to skin cancer and premature aging.

6
Vocabulary
  • Lymphatic System tissues and organs that
    produce, store, and carry white blood cells that
    fight infections and other diseases.
  • Lymph Node mass of lymphatic tissue responsible
    for filtering lymph and storing white blood cells
    (lymphocytes).

7
Vocabulary
  • UVB radiation radiation that causes sunburn,
    also believed to skin cancer.
  • Sunscreen a substance that helps protect the
    skin from the suns harmful rays by reflecting,
    absorbing, and scattering UV rays.
  • Broad Spectrum sunscreens that protect against
    UVA and UVB rays. (Most only protect against UVB)

8
Types of Skin Cancer
  • Basal Cell Carcinoma (BCC)
  • Squamous Cell Carcinoma (SCC)
  • Melanoma causes the most deaths from skin
    cancer, is associated with indirect DNA damage.

9
Identifying Skin Cancer
  • Keep an eye out for
  • lesions in the skin that do not heal,
  • ulcers in the skin
  • discoloration, and changes in existing moles
  • Painful itching of skin (especially in sun
    exposed areas)

10
Some Examples
  • Basal cell
  • carcinoma
  • Squamous Cell
  • Carcinoma
  • Melanoma

11
  • Understand the Risks
  • Basal Cell and Squamous Cell Carcinomas are
    usually not fatal. They usually do not
    metastasize and can be removed fairly easily.
    The sooner the diagnosis, the better though.
  • Melanoma is the most deadly type of skin cancer.
    If it isnt caught soon enough it will often
    spread throughout the body and can lead to death.
    Melanoma is broken down into 4 stages.

12
Stages of Melanoma
--
  • The stages of Melanoma are based on how large the
    tumor is and how far throughout the body the
    cancerous cells have spread.
  • Stage 0 only in the outer layer of skin cells
  • Stage 1 less than 1 mm thick melanoma cells
    have not spread to nearby lymph nodes
  • Stage 2 between 1 and 2 mm think not spread

13
Stages of Melanoma
  • Stage 3 melanoma cells have spread to nearby
    tissues or lymph nodes
  • Stage 4 melanoma cells have spread to other
    organs, lymph nodes, or skin not near the
    original tumor.

14
Pop Quiz!
  • Which is the most dangerous type of skin cancer?
  • a. Basal cell carcinoma
  • b. Squamous cell carcinoma
  • c. Malignant melanoma

15
Risk Factors
  • Overexposure to UV radiation
  • UVB shorter wavelengths affecting the outermost
    layers of skin, known to cause sunburns.
    Exposure to UVB light is said to cause Basal Cell
    Carcinoma and Squamous Cell Carcinoma.
  • UVA longer wavelengths that penetrate into the
    skin and cause tanning as well as the DNA damage
    linked with Malignant Melanoma.

17
Risk Factors Contd
  • Chronic, non-healing wounds (especially burns)
    can develop into SCC.
  • Genetic predisposition
  • History of severe burns as a child
  • Older age
  • Being fair-skinned, prone to burning
  • Being born with moles (check them for changes)

18
Protect Yourself in the Sun!
  • Sun exposure between 10am and 4pm is the most
    intense and most harmful. Find shade or carry an
    umbrella during these hours.
  • Wear hats and sunglasses to protect your face.
  • Use foundation or powder with SPF in it.
  • Wear sunscreen, but dont depend on it.
    Sunscreen that is absorbed into the skin does not
    protect against the indirect DNA damage linked
    with Malignant Melanoma.

19
  • Understand SPF
  • SPF tells you how long it will take to burn with
    sunblock compared to how long it would take
    without. Ex I burn in 4 minutes. If I wear SPF
    10, I shouldnt burn until after 40 minutes.
  • Use Broad Spectrum sunblock to protect against
    both UVB UVA.
  • For best protection apply sunscreen 15 30
    minutes before sun exposure and REAPPLY after 15
    30 minutes of sun exposure.

20
Dont be fooled by Tanning Bed Claims
  • Claim Tanning beds control light exposure
    allowing users to develop a protective and safe
    base tan.
  • Truth Light in tanning beds gives off 3 times
    as much UVA light. Common side effects of UVA
    exposure
  • Malignant Melanoma
  • loss of elasticity in skin (helps skin appear
    firm)
  • premature aging
  • wrinkles
  • damage to the immune system

21
  • Claim they are safer because they limit UVB
    exposure that is linked with burning, BCC, and
    SCC.
  • Truth even the limited UVB exposure can still
    result in burning, meanwhile the UVA exposure
    continues to do more damage below the surface.
  • Truth Scientists say that even tanning in
    moderation produces the same harmful effects, as
    would a burn

22
Harsh Reality
  • People continue to sunbathe and visit tanning
    beds despite all the information.
  • Melanoma in the United States 2007 Estimates
  • New Cases - 59,940
  • Deaths - 8,110

23
Still want a tan? Learn how to fake it!
  • Sunless tanners come in lotions sprays and creams
    that are applied and soak into the skin.
  • Most contain the chemical dihydroxyacetone (DHA)
    which causes the dead surface cells of the skin
    to darken, simulating a tan. Results usually
    last for several days.
  • Sunless tanners can be applied at tanning salons
    or at home.

24
  • Sunless tanning booths, ask these important
    questions
  • Will my eyes and surrounding area be protected?
  • Will my nose, mouth, and ears be protected?
  • Will I be protected from inhaling the tanning
    spray through my nose or mouth?
  • If any answer is no, find a different salon.
  • Be sure to watch and pay close attention to the
    video before hand.
  • Follow instructions completely for the best
    results.

25
  • At-home tanning
  • Look for products that come in a variety of
    shades and find one that best matches your skin
    tone.
  • Look for even application techniques to avoid
    streaks.
  • Some spray on enabling you to reach difficult
    places.
  • Lotions that gradually darken over multiple
    applications can look more natural.
  • Exfoliate before applying instead of after.
  • Lotions may be sticky feeling or smell a little
    funny, so apply before bed and let them work
    while you sleep.
  • Dry skin soaks up the lotion and can appear
    yellow or orange later. Be sure to exfoliate and
    moisturize areas and avoid overapplying tanning
    lotion.
  • Wash your hands IMMEDIATELY after applying lotion.

26
Popular Products
27
But wait, we still need the sun!!!
  • Contrary to all the latest media about avoiding
    the sun at all costs, our bodies actually need
    sunlight. So dont completely give up on your
    tan yet!

28
How Our Bodies Use Sunlight
  • Vitamin D synthesis our bodies use sunlight to
    manufacture Vit. D, a nutrient found in very few
    foods naturally.
  • Vitamin D is very important to bone growth and
    maintenance.
  • Vitamin D deficiency can result in these
    diseases
  • Rickets (retarded bone growth and calcification
    in kids)
  • Osteomalacia (adult form of Rickets where bones
    soften)
  • Osteoporosis (reduced bone density causing easily
    broken bones.)

29
How Our Bodies Use Sunlight
  • Mood Boost its said that just 15 minutes in
    the sun will make anyone feel better!
  • SAD (Seasonal Affective Disorder) can result from
    too little time outdoors.
  • So there is a reason we all want to vacation in
    tropical places! Its good for our health!

30
  • How much sunshine is enough?
  • UV-B rays are most responsible for Vit. D
    synthesis, so tanning beds may not cut it.
  • 10-15 minutes on a clear summer day, a few times
    a week should be enough.
  • Clouds, sunblock, time of year, and darkness of
    skin will affect how much exposure is necessary.
