Title: Sun Safety

Sun Safety Skin Cancer Prevention
Types of Skin Cancer
  • Basal Cell Carcinoma (BCC)
  • Squamous Cell Carcinoma (SCC)
  • Malignant Melanoma causes the most deaths from
    skin cancer, is associated with indirect DNA

Signs and Symptoms
  • Keep an eye out for lesions in the skin that do
    not heal, ulcers in the skin, discoloration, and
    changes in existing moles.

Identifying the different types
  • Basal cell carcinoma usually looks like a raised,
    smooth, pearly bump on the sun-exposed skin of
    the head, neck or shoulders. Sometimes small
    blood vessels can be seen within the tumor.
    Crusting and bleeding in the center of the tumor
    frequently develops. It is often mistaken for a
    sore that does not heal.

  • Squamous cell carcinoma is commonly a red,
    scaling, thickened patch on sun-exposed skin.
    Ulceration and bleeding may occur. When SCC is
    not treated, it may develop into a large mass

  • Malignant Melanoma are brown to black looking
    lesions. Signs that might indicate a malignant
    melanoma include change in size, shape, color or
    elevation of a mole. The appearance of a new mole
    during adulthood, or new pain, itching,
    ulceration or bleeding of an existing mole should
    be checked.

  • Malignant Melanoma begins on the surface of the
    skin where it is easy to see and treat. If given
    time to grow, melanoma can grow down into the
    skin, ultimately reaching the blood and lymphatic
    vessels, and spreading around the body
    (metastasize), causing life-threatening illness.

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

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 indirect
    DNA damage linked with Malignant Melanoma.

  • UVB rays
  • Look like
  • Cause
  • UVA rays
  • Look like
  • Cause

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)

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.

  • 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.

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
  • Malignant Melanoma
  • loss of elasticity in skin (helps skin appear
  • premature aging
  • wrinkles
  • damage to the immune system

  • Claim they are safer because they limit UVB
    exposure that is linked with burning, BCC, and
  • 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

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

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.

  • Sunless tanning booths, ask these important
  • 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

  • At-home tanning
  • Look for products that come in a variety of
    shades and find one that best matches your skin
  • Look for even application techniques to avoid
  • Some spray on enabling you to reach difficult
  • 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
  • Wash your hands IMMEDIATELY after applying lotion.

Popular Products
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!

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
  • Vitamin D deficiency can result in these
  • Rickets (retarded bone growth and calcification
    in kids)
  • Osteomalacia (adult form of Rickets where bones
  • Osteoporosis (reduced bone density causing easily
    broken bones.)

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!

  • 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.
