A.

If you have a question or concern about something on your skin, see your doctor. Thinking of "ABCD" can help you remember what to watch for:


  • Asymmetry -- The shape of one half does not match the other

  • Border -- The edges are often ragged, notched, blurred, or irregular in outline; the pigment may spread into the surrounding skin.

  • Color -- The color is uneven. Shades of black, brown, and tan may be present. Areas of white, grey, red, pink, or blue also may be seen.

  • Diameter -- Melanomas are usually larger than the eraser of a pencil (1/4 inch or 5 millimeters).


Also pay attention to evolution -- has the mole changed over time?
