How do I know if a mole is dangerous?

Be especially concerned if a mole is changing color, size, or shape. Other suspicious symptoms include itching or burning. A mole that bleeds with minimal trauma is also suspicious.

Self examination of moles is extremely important. Any mole, which is suspicious, should be examined by a dermatologist. When inspecting a mole, evaluate the following features:

• Asymmetry -- Examine the mole for uniformity of shape, color, and size.
• Borders -- Examine the mole for any irregularity in the borders.
• Color -- Examine the mole for a change in color or a mixture of colors, especially black, grey, blue, or red.
• Diameter -- A mole would be suspicious if the diameter is greater than 6mm (about the size of a pencil eraser).

These are the ABCD's of mole evaluation.
