Melanoma skin cancer sign: Border that is irregular

A normal mole and a mole with a ragged, notched border

Melanoma is the most serious type of skin cancer. The most important warning sign of melanoma is a change in the size, shape, or color of a mole or other skin growth, such as a birthmark.

Border irregularity is one thing to watch for. Call your doctor if any skin growth has developed ragged, notched, or blurred edges.
