How do I know if a mole is dangerous?

Answered by the AskDoc Medical Team · Medically reviewed under our Medical Director, MBBS

Use the ABCDE check: Asymmetry, Border irregularity, Color variation within one mole, Diameter beyond a pencil eraser, and Evolving, any change in size, shape, color, or new itching and bleeding.

The strongest single signal is change. A mole that looks different from its neighbors, the ugly duckling, earns attention even if it fails the other letters.

Any evolving or bleeding mole should be examined promptly; caught early, melanoma is highly curable. Photograph suspicious spots monthly with a coin for scale so change becomes visible instead of debatable.

The one skin product doctors push

Broad-spectrum SPF 50, worn daily, does more against skin aging and skin cancer risk than any cream sold above it. The best sunscreen is the one you will actually wear every morning.
