When evaluating moles and other skin lesions for cancer, dermatologists and other health care providers look for these characteristics:
A: Asymmetry of a skin lesion (one half is not the same shape as the other half)
B: Border irregularity (the edges of the lesion are uneven)
C: Color variations (the lesion is multicolored rather than all one color)
D: Diameter of greater than 1/4-inch, about the size of an eraser on the end of a pencil. Larger lesions are more likely to be cancerous.
If you have any moles or skin lesions that are growing or changing, or if they have any of these characteristics, have them checked out.
