Visible Warning Signs

Unlike some forms of cancer, skin cancer can be easily seen. Here are some visible warning signs you should be on the lookout for:

A. Asymmetry—one half unlike the other half.
B. Border irregular—scalloped or poorly circumscribed border.
C. Color varied from one area to another; shades of tan and brown, black sometimes white, red, or blue.
D. Diameter larger than 6 mm as a rule (diameter of pencil eraser).

If you find any suspicious areas, you should show them to your doctor.
