Skin Cancer

  • Most common cancer in US

  • Fastest increasing cancer in US

  • 1,000,000 people have some form

  • of skin cancer


Skin cancer

Skin Cancer

  • Three main types

  • -- basal-cell

  • -- squamous-cell

  • -- melanoma

  • The main difference between melanoma and other skin cancers is that melanoma can

  • spread to distant body sites including the lungs, liver or brain.


Skin cancer

Basal Cell Carcinoma


Skin cancer

Squamous Cell Carcinoma


Skin cancer

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.


Skin cancer

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

  • any other cancer

  • On average, one melanoma death in the U.S.

  • per hour

Asymmetry

One half does not match

Skin cancer

Border irregularity

The edges are ragged, notched,

or blurred.


Skin cancer

The pigmentation is not uniform.

Shades of tan, brown, or black are

present. A mottled appearance.


Skin cancer

or continuing increase in size is

of special concern.

Skin cancer

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


Skin cancer

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.
