Moles warn of cancer

If you have a new mole after the age of 30, you should consider having it checked out as it could be a sign of a malignant skin tumor.

The ABCDE tips dermatologists use to identify dangerous moles: Moles that are asymmetrical (Asymmetry), have irregular borders (Borders), have more than one color (Color), are larger than a pencil eraser (Diameter) in diameter, and change over time (Evolving).

This is a good method, but it is not always effective. "There are times when the signs of cancer do not match the ABCDE method. For example, many cases of malignant tumors are smaller than a pencil eraser," says dermatologist Clifford Perlis at Fox Chase Cancer Center in Philadelphia.

Here are some signs to help you monitor your skin better. A mole may be malignant if:

Newly appeared

“After age 30, you typically don’t get new moles,” says Dr. Perlis. If a new mole forms, have it checked out by your doctor. Many melanomas appear on previously healthy skin; only 28 percent develop from existing moles.

Itching, bleeding, or pain

A normal mole will not cause any pain. When it causes discomfort such as itching, bleeding or pain, you should see a doctor immediately.

Has unusual color

Many people think of melanomas as brown, but sometimes they are pink or flesh-colored. Clear, pearly, and black moles can also signal cancer.

Moles can be harmless when they look like warts. They don’t itch or hurt, but they can peel off and come back. In some cases, they can look like melanomas but aren’t. It’s best to have a professional help you tell the difference.
