    The ABCDEs of melanoma

    The ABCDEs of melanoma skin cancer are:

    • Asymmetry. One half doesn't match the appearance of the other half.
    • Border irregularity. The edges are ragged, notched, or blurred.
    • Color. The color (pigmentation) is not uniform. Shades of tan, brown, and black are present. Dashes of red, white, and blue add to a mottled appearance.
    • Diameter. The size of the mole is greater than 1/4 inch (6 mm), about the size of a pencil eraser. Any growth of a mole should be evaluated.
    • Evolution. There is a change in the size, shape, symptoms (such as itching or tenderness), surface (especially bleeding), or color of a mole.
