5. What is Skin Cancer? Skin Cancer is cancer that forms in tissues of the skin There are three types of Skin Cancer  Basal Cell Carcinoma  Squamous Cell Carcinoma  Melanoma

6. Basal Cell Carcinoma Accounts for 80% of all skin cancers in the U.S Arises from the basal cells, small round cells found in the base of the epidermis Slow-growing cancer that seldom spreads to other parts of the body, and generally is readily treatable If not treated may erode into surrounding structures

7. Squamous Cell Carcinoma The second most common form of skin cancer Approximately 250,000 new cases per year Begins in the squamous cells, which are thin flat cells that look like fish scales and are found in the tissues that forms the surface of the skin

8. Melanoma Is the most serious form of skin cancer Can be curable if detected early However, if it is not treated it can spread to other part of the body an be fatal. It is estimated that in 2007  8,110 fatalities  5,220 in men  2,800 in women
