Skin cancer is the most common cancer in the United States. Several different types exist: basal cell carcinoma, squamous cell carcinoma, and melanoma. Basal cell and squamous cell carcinoma are the most common and, with timely treatment, they usually do not lead to major problems or death. Melanoma is less common but is more difficult to treat and can be deadly. Persons with fair skin, light hair and eye color, or freckles or who sunburn easily have a higher risk for skin cancer than do people with darker skin.
