Basal Cell Carcinoma
Basal cell carcinoma accounts for over 75% of all cancers, and is the most common form of cancer worldwide. It occurs in middle-aged and older adults, especially those who are fair-skinned. It is more common in people who have regular prolonged sun exposure.
Squamous Cell Carcinoma
Squamous cell carcinoma accounts for about one in five skin cancers and together with basal cell carcinoma causes ninety percent of all cancers. This cancer originates in the upper part of the epidermis. The risk of developing squamous cell carcinoma increases with years of prolonged sun exposure, especially sun burns and fair skin color.
Although melanoma accounts for only 4% of skin cancers, it is responsible for more than 80% of all skin cancer deaths. In fact, one person dies of melanoma every hour in this country. Melanoma is increasing at a faster rate than any other cancer in the United States. When detected early, however, melanoma is curable.
