Dermatologists say the most important sign of skin cancer is any change in an existing spot or the appearance of a new one, regardless of cancer type.
Change in skin spots is the universal warning sign for all major skin cancers
Basal cell carcinoma, squamous cell carcinoma, and melanoma each present differently, but dermatologists agree that change—such as growth, bleeding, itching, tenderness, or a sore that won’t heal—should prompt immediate evaluation. Dr. Michael Christopher of Ironwood Dermatology & Aesthetics in Tucson emphasized that this applies equally to long-standing moles and entirely new spots. “The number-one sign is change,” he said, noting that early detection dramatically improves outcomes, especially for melanoma, which has a over 99% survival rate when caught before spreading.

Doctors stress that self-checks and prompt visits save lives
Dr. Adam Friedman of George Washington University School of Medicine explained that non-melanoma skin cancers often appear as sores, bumps, or irritated patches rather than mole-like growths, making them easy to overlook. Despite their differences, all three types share the same critical early indicator: alteration in the skin’s surface. The American Cancer Society reinforces this, citing near-perfect survival for early-stage melanoma. Dermatologists urge patients not to wait for pain or obvious symptoms, as change itself is the earliest and most reliable clue.

What should I look for when checking my skin?
Watch for any change in existing moles or spots—such as size, shape, color, bleeding, itching, or failure to heal—and any new spot that appears unexpectedly.
How urgent is it to see a dermatologist if I notice a change?
Very urgent; early detection of melanoma before it spreads leads to a survival rate over 99%, so prompt evaluation is critical even if the change seems minor.
