The best way to find skin cancer early is to keep an eye on your skin, especially moles. The ABCDE rule (see below) can help you remember what to look for when you're checking any moles on your skin. If you notice any of these signs, talk to your doctor right away.
Signs of Skin Caner: THE ABCDE Rule
A for asymmetry: A mole that, when divided in half, doesn't look the same on both sides.
B for border: A mole with edges that are blurry or jagged.
C for color: Changes in the color of a mole, including darkening, spread of color, loss of color, or the appearance of multiple colors such as blue, red, white, pink, purple or gray.
D for diameter: A mole larger than 1/4 inch in diameter.
E for elevation: A mole that is raised above the skin and has an uneven surface.
