How Can You Tell If A Mole Is Cancerous (Malignant melanomas)?

Although most skin growths are not cancer, it's important to check with the doctor about new growths or changes in old growths. When growths become cancerous, they may change in size or color, or become sores that do not heal.

Doing a regular skin self-examination is a good way to monitor the skin for early symptoms of skin cancer. Skin self examination is especially important for people who have had skin cancer. It can detect new cancers, and recurrences of past cancer, at an early and most curable stage.

Malignant melanomas usually form on the trunk (the area of the body between the neck and the hips) or legs. These areas don't get constant sun exposure. Rather, they are areas that get periodic intense exposure and sun burn.

-Moles and freckles are usually light to dark brown and have a clear-cut edge or border.

-Melanomas usually are multi-colored. The may combine different shades of brown and black, sometimes with areas of red, white or blue.
