Board-certified cardiologist and dermat reveals 10 signs of skin cancer

Skin cancer is common globally. Early detection significantly improves treatment success. Dr. Jeffrey Nesbell and Dr. Evan Levine highlight key warning signs. Look for sores that don't heal, pearly bumps, rough patches, firm red nodules, and scar-like areas. Melanoma signs include asymmetry, irregular borders, varied color, large diameter, and evolving moles. The 'Ugly Duckling' sign is also important.
