One of the first things that raises red flags about this mole is the size. The rule of thumb is that anything larger than a pencil eraser (1/4 inch or 6mm) may be abnormal and needs to be evaluated by a dermatologist. This mole is also considered to be abnormal because it has varying shades of brown and lacks a uniform, symetrical border.
