The ABCDE's of Skin Cancer

By

Updated April 16, 2007

A- Asymmetry:

Normal moles or freckles are completely symmetrical. If you were to draw a line through a normal spot, you would have two symmetrical halves. In cases of skin cancer, spots will not look the same on both sides.

B- Border:

A mole or spot with blurry and/or jagged edges.

C- Color:

A mole that is more than one hue is suspicious and needs to be evaluated by a doctor. Normal spots are usually one color. This can include lightening or darkening of the mole.

D- Diameter:

If it is larger than a pencil eraser (about 1/4 inch or 6mm), it needs to be examined by a doctor. This is includes areas that do not have any other abnormalities (color, border, asymmetry).

E- Elevation:

Elevation means the mole is raised above the surface and has an uneven surface.
