How can you identify a cancerous melanoma?

ANSWER

  • The following easy-to-remember guideline, "ABCDE," is useful for identifying malignant melanoma: Asymmetry -- One side of the lesion does not look like the other.
  • Border irregularity -- Margins may be notched or irregular.
  • Color -- Melanomas are often a mixture of black, tan, brown, blue, red, or white.
  • Diameter -- Cancerous lesions can be larger than 6 mm across (about the size of a pencil eraser), although with early detection they will not reach this size.
  • Evolution -- has a mole changed over time?
