May is Skin Cancer Awareness Month. Skin cancer is the most common type of cancer in the United States. It occurs in more than a million people each year, including many older people. Approximately 65%–90% of melanomas, the most serious form of skin cancer, are caused by exposure to ultraviolet light or sunlight. With summer just around the corner, now is a good time to review ways to protect yourself against overexposure to the sun and to learn some of the facts about skin cancer.
