While signs and symptoms of melanoma skin cancer 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?
