  1. Skin Cancer: Giana Bowers Mr. Case

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

  3. 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.

  4. Basal Cell Carcinoma

  5. Squamous Cell Carcinoma

  6. 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.

  7. 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

  8. Top 8 Invasive Cancers in the U.S. Prostrate Breast Lung Colon Lymphoma Bladder Melanoma Rectal

  9. ABCDs • Asymmetry • Border • Color • Diameter

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

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

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

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

  15. Malignant Mole

  16. 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

  17. 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.
