•Most common cancer in US
•Fastest increasing cancer in US
•1,000,000 people have some form
of skin cancer
Skin Cancer
•Three main types

The main difference between melanoma and
other skin cancers is that melanoma can
spread to distant body sites including the
lungs, liver or brain.
Basal Cell Carcinoma
Squamous Cell Carcinoma
Melanoma
*Seventh most common cancer in the
United States.
*One out of every 105 Americans born in 1991
will develop malignant melanoma
(compared to 1 out of 1,500 in 1935).
*The number of new cases of melanoma has more
than doubled since 1973.
Melanoma (cont.)
•Most common cancer in young adults age
25-29
•Among women age 30-35, incidence is
exceeded only by breast cancer
•Incidence increasing 4% annually, higher than

Ultraviolet (UV) Radiation
The sun radiates energy over a broad spectrum of
wavelengths. UV radiation, which has a shorter
wavelength than visible blue or violet light, is
responsible for sunburns and other health effects:
•Skin cancer
•Cataracts
•Suppression of the immune system
•Premature aging of the skin
Sunburns
An increased risk of melanoma
related to the frequency of sunburns
during all periods of life. More than five
sunburns doubled the melanoma risk,
irrespective of the time in life.
Prevention of Skin Cancer
