Melanoma skin cancer sign: Evolution

Three images that show a skin growth getting larger over time

Melanoma is the most serious type of skin cancer. The most important warning sign of melanoma is a change in a mole or other skin growth, such as a birthmark.

  • Evolution is another word for "change." Call your doctor if you notice any changes such as:
    • A change in the size, shape, or color of a mole.
    • A change in symptoms, such as a mole that becomes itchy or tender or that bleeds.
