ABCDEs of Melanoma Detection: How to Tell if a Mole Is Dangerous

Look for Danger Signs in Pigmented Lesions of the Skin

Consult your dermatologist immediately if any of your moles or pigmented spots exhibit:

An asymmetrical mole may be dangerous
Asymmetry–one half unlike the other half.

A mole with an irregular border may be dangerous
Border –irregular, scalloped or poorly circumscribed border.

A mole with multiple shades of color may be dangerous
Color — varied from one area to another; shades of tan and brown, black; sometimes white, red or blue.

A mole with a larger than normal diameter may be dangerous
Diameter — while melanomas are usually greater than 6mm in diameter (the size of a pencil eraser) when diagnosed, they can be smaller.  If you notice a mole different from others, or which changes, itches, or bleeds (even if it is small) you should see a dermatologist.

Evolution — If you notice a mole that is growing or which changes, itches, or bleeds you should see a dermatologist.

They may be signs of malignant melanoma!
