The best defense against any type of skin cancer is finding and treating it early. When squamous or basal cell skin cancers are found early, there is nearly a 100 percent chance for cure while for melanoma, there is nearly a 97 percent chance.
The two most common types of skin cancer are basal cell and squamous cell, usually referred to as non-melanoma skin cancers.
Basal cell accounts for more than 90 percent of all skin cancers in the U.S. It is a slow-growing cancer that seldom spreads to other parts of the body.
Squamous cell is much less common than basal cell and is more likely to spread to other parts of the body.
A third type of skin cancer, melanoma, is the most serious of all skin cancer types because it is more likely than non-melanoma skin cancers to invade healthy tissue and spread to other parts of the body. Melanomas usually occur on or around existing moles.
