Melanoma Symptoms

While signs and symptoms of melanoma vary from person to person, the ABCDEFs of melanoma symptoms are an easy way to learn the early signs of melanoma.

Asymmetry: Is one side of the mole different than the other?

Border irregularity: Are the edges ragged or irregular?

Color variation: Is the mole getting darker? Is part of it changing color or does it contain several colors?

Diameter: Is the mole bigger than the diameter of a pencil eraser?

Evolution: Is the mole growing in width or height?

Feeling: Has the sensation around a mole or spot changed?

Show any suspicious skin area, non-healing sore or new or changing mole or freckle to your doctor right away.
