The ABCDs 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.
