  1. Skin Cancer: What You Should Know Randy R. Weigel University of Wyoming Cooperative Extension Service

  2. Skin Cancer • Most common cancer in US • Fastest increasing cancer in US • 1,000,000 people had some form • of skin cancer in 2003

  3. 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.

  4. The Skin & Melanoma

  5. Basal Cell Carcinoma

  6. Squamous Cell Carcinoma

  7. 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.

  8. 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

  9. 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.

  11. 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?

  12. ABCDs • Asymmetry • Border • Color • Diameter

  13. Asymmetry One half does not match the other half.

  14. Border irregularity The edges are ragged, notched, or blurred.

  15. Color The pigmentation is not uniform. Shades of tan, brown, or black are present. A mottled appearance.

  16. Diameter Greater than ¼ inch. Any sudden or continuing increase in size is of special concern.

  17. Normal Mole

  18. Malignant Mole

  19. 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

  20. 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)

  21. What Can You Do? • Increasing Awareness • -- that melanoma is serious • -- the importance of • prevention • -- self-exams • -- getting in and getting it • treated
