What does skin cancer look like?

There are 4 criteria to diagnose what kind of mole you have, and the criteria start with A, B, C, and D.

The ABCDs are:
* A - Asymmetry (most common moles are roundish and symmetrical)
* B - Border (skin cancers may have uneven borders)
* C - Color (cancer can be varied shades of brown, tan or black and also red, white, and blue)
* D - Diameter (if a spot is larger than a pencil eraser that's a sign it may be cancer)
