When should I worry about a mole?

Use the ABCDE rule: Asymmetry, Border irregularity, Color variation, Diameter over 6mm, Evolving. Any change in an existing mole — or a new one after age 40 — gets checked.

Follow-up questions

How often should I see a dermatologist?

Yearly if you have many moles, fair skin, or a family history of melanoma. Otherwise every 2–3 years.

Does sunscreen actually prevent skin cancer?

Yes — regular use of SPF 30+ reduces melanoma risk by around 50% in trials.
