Melanoma skin cancer sign: Asymmetry

A normal mole and a mole with halves that do not match

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.

Asymmetry is one thing to watch for. This means that one half doesn't match the other half. Call your doctor if you notice that:
- One half of a mole doesn't match the other half.
