12 Signs of Skin Cancer

3. Asymmetrical moles

Asymetrical moles with irregular borders may be a symptom of melanoma. Though not the most common type of skin cancer, melanoma is the most serious. It not only affects the skin, but can also affect the eyes, the palms of the hands, and the fingernail beds. Women often develop melanomas on the lower legs, while men tend to see them on the chest, back, head, and neck. Moles that change in size, color, or shape can indicate skin cancer. A mole that bleeds, itches or changes in any way needs evaluation to rule out melanoma. A normal mole is about a ¼-inch in diameter, the size of a pea. Moles that grow larger warrant medical investigation. Doctors are seeing many more cases of this type of skin cancer in people under 40.
