  1. Types of Skin Cancer

  2. 3 Types of Skin Cancer • Basal Cell Carcinoma • Squamous Cell Carcinoma • Melanoma

  3. Basal Cell Carcinoma • Non-melanoma skin cancer • Small, fleshy bump or nodule on the head, neck, or hands • Accounts for more than 90 percent of all skin cancers in the United States • Usually treated successfully—95% (American Academy of Dermatology)

  4. Who is at Risk? • Most common skin cancer found in Caucasians • Light hair, eyes, and complexions • Do not tan easily

  5. Squamous Cell Carcinoma • Non-melanoma carcinoma • May appear as nodules, or as red, rough/scaly/crusted patches of skin • Usually treated successfully—95% (American Academy of Dermatology)

  6. Who is at Risk? • Second most common skin cancer found in Caucasians • Usually found on fair-skinned persons

  7. Melanoma • May also be called cutaneous melanoma or malignant melanoma • Cancer cells are found in the melanocytes • Incidence of melanoma is lower than other types of skin cancer • Highest death rate (75 percent of all deaths from skin cancer)

  8. Who is at Risk? • Blond or red hair • Blue eyes • Fair complexion • Family history of melanoma • Many ordinary moles (more than 50) • Many freckles • Immunosuppressive disorder • Sun exposure • Inability to tan

  9. Other Factors • Heredity • Occupational exposure to coal tar, pitch, creosote, arsenic compounds, or radium. • Elevation - ultraviolet light is stronger as elevation increases • Latitude - the rays of the sun are strongest near the equator. • Cloud cover - places with regular cloud cover may actually reduce UV

  10. Is it a mole or melanoma? • Use the ABCDE rule • A = asymmetry • B = borders • C = color variation • D = diameter • E = evolving (changing)

  11. Things to look for • A=Asymmetry (the left side of the lesion is unlike the right side)

  12. Things to look for • B=Border Irregularity (the lesion has a scalloped or poorly defined border)

  13. Things to look for • C=Color Variation (not all parts of the lesion are the same color; within the lesion may be patches of tan, brown, black, pink, white or blue)

  14. Things to look for • D=Diameter (while melanomas are usually greater than 6mm in diameter when diagnosed, they can be smaller.  If you notice a mole different from others, or which changes, itches or bleeds even if it is smaller than 6mm, you should see a dermatologist)

  15. Things to look for • E=Evolving (Has the mole or skin lesion changed color, size or shape? Does it looks different than the others?)
