Skin cancers including melanoma, basal cell carcinoma, and squamous cell carcinoma, often start as changes to your skin. They can be new growths or precancerous lesions -- changes that are not cancer but could become cancer over time.
These small, scaly patches are caused by too much sun, and commonly occur on the head, neck, or hands, but can be found elsewhere.
Risk can be reduced of skin cancer by limiting or avoiding exposure to ultraviolet radiation. Checking your skin for suspicious changes can help detect skin cancer at its earliest stages.
See your doctor if you notice any changes to your skin.
