Usually, the first sign of skin cancer is a change in the size, shape, color or feel of an existing mole. Many melanomas have a black or blue-black area. A melanoma can also appear as a new mole that is abnormal, black or just "funny-looking."
Know your ABCDEs
The ABCDE guide can help you figure out if you have any spots on your body that should be checked by a dermatologist.
A - Asymmetry
One half of the area does not match the other half.
B - Border
The edges are irregular, ragged, or blurred.
C - Color
The color varies from one area to another and may include shades of tan, brown, or black, sometimes with patches of red, white, or blue.
D - Diameter
The spot is larger than 6 millimeters across – about the size of a pencil eraser.
E - Evolution
Any mole that is changing in color, size, or shape
It is also important to watch for spots, bumps, moles, freckles, or patches of skin that itch, ooze, or bleed. If you notice any unusual or worrisome changes, make an appointment with a dermatologist for a thorough screening exam. Skin cancer is very treatable when caught early.
