The American Academy of Dermatology has developed an easy-to-use method to evaluate your skin for melanoma. Look for the "ABCDEs":
- Asymmetry: One half of the spot is not shaped like the other half.
- Border irregularity: A poorly defined or "scalloped" border.
- Color: Shades of tan, brown, black and sometimes red, white and blue, vary across the spot.
- Diameter: The spot is larger than six millimeters, the diameter of a pencil eraser, however, skin cancers can also be smaller.
- Evolving: The mole looks different from the other moles on the body and is changing in size, shape or color.
