What You Should Know

slide2

Skin Cancer

  • Most common cancer in US
  • Fastest increasing cancer in US
  • 1,000,000 people had some form
  • of skin cancer in 2003
slide3

Skin Cancer

  • Three main types
  • -- basal-cell
  • -- squamous-cell
  • -- melanoma
  • The main difference between melanomas and other skin cancers is that melanoma can
  • metastasize (spread) to distant body sites
  • including the lungs, liver or brain.
slide7

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.

slide8

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
slide9

Melanoma (cont.)

  • Increase is the result of recreational sun
  • exposure, thinning of the ozone layer, and
  • better detection.
  • In 2001, an estimated 48,000 new cases
  • of melanoma occurred.
  • In 2003, 54,000 new cases occurred
  • In 2000, skin cancer claimed the lives of
  • 9,600 people.

Wyoming and Melanoma

  • 72 people died from melanoma cancer
  • from 1992-1996.
  • Wyoming ranked 2nd in the U.S. for
  • melanoma deaths from 1992-1996.
  • Wyoming ranked 5th in the U.S. for melanoma
  • deaths from 1996-2000
  • Which Wyoming counties had the highest
  • % of melanoma cases?
slide12

ABCDs

  • Asymmetry
  • Border
  • Color
  • Diameter
slide13

Asymmetry

One half does not match

the other half.

slide15

Border irregularity

The edges are ragged, notched,

or blurred.

slide17

Color

The pigmentation is not uniform.

Shades of tan, brown, or black are

present. A mottled appearance.

slide19

Diameter

Greater than ¼ inch. Any sudden

or continuing increase in size is

of special concern.

slide23

Ultraviolet (UV) Radiation

UVA – UVB - UVC

  • 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
slide29

Sunburns

…We found 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.

British Journal of Dermatology

(2001)

slide30

What Can You Do?

  • Increasing Awareness
  • -- that melanoma is serious
  • -- the importance of
  • prevention
  • -- self-exams
  • -- getting in and getting it
  • treated
