Early Detection of Skin Cancer


Learn if a Mole is Cancerous


For the best possible outcome, detecting skin cancer early is critical. Consult your healthcare provider for moles that cause you concern, but you cannot run to your doctor for every little mole. Learn to perform self–diagnoses by examining yourself regularly and thoroughly for new spots or growths, or changes in existing spots or growths. Follow the "ABCDE" rubric below to determine if an abnormal or suspicious growth could be cancerous:


A – for Asymmetry of moles and skin spots. A mole that, when divided in half, doesn't look the same on both sides.

B – for Border of moles and skin spots become irregular or blurred.

C – for Color of a mole, including darkening, spreading of color, loss of color, or the appearance of multiple colors such as blue, red, white, pink, purple, or gray.

D – for Diameter of a mole or skin spot becomes enlarged, especially if it is larger than 1/4–inch in diameter (about the size of a pencil eraser).

E – for Evolving of a mole that is raised above the skin and has an uneven surface.


These are the exact same skin spot characteristics that your dermatologist will look for when examining you. Learn to examine yourself thoroughly and often. Examine yourself under a bright light. Use a full length mirror and a hand mirror so you can thoroughly examine your back, back of your arms, legs, etc.


Don't be a hypochondriac and believe that every little mole or sun spot is cancerous. And don't be a fool and misjudge a cancerous mole as being benign either. Use your good common sense (ABCDE), and if it looks suspicious, see your healthcare provider as soon as possible.
