The most deadly form of skin cancer is malignant melanoma. It can be identified by certain types of pigmented spots. Asymmetry in which one-half of the pigmented spot does not match the other half. Border irregularity. Color varies from one area to another. Diameter is larger than a pencil eraser.

Sun exposure should always be limited but especially if a member of your family has had melanoma. Research shows that your likelihood of getting the disease is 3 to 4 times greater if you have a family member who has had it.
