Basal cell carcinoma is the most common form of skin cancer. In fact, it is the most common of all cancers. One out of every three new cancers is a skin cancer, and the vast majority are basal cell carcinomas. Chronic exposure to sunlight is the cause of almost all basal cell carcinomas, which occur most frequently on exposed parts of the body -- the face, ears, neck, scalp, shoulders, and back. Anyone with a history of frequent sun exposure can develop basal cell carcinoma. People who have fair skin, light hair, and blue, green, or gray eyes are at highest risk. Those whose occupations require long hours outdoors or who spend extensive leisure time in the sun are in particular jeopardy. Basal cell carcinoma can have varying characteristics, including: an open sore that bleeds or crusts for several weeks; a reddish patch or irritated area that itches or hurts; a shiny bump or nodule - often confused with a mole; a pink growth with elevated borders and a crust in the center - often with multiple tiny blood vessels; or a scar-like area with poorly defined borders. Ask your Oral & Maxillofacial Surgeon about suspected areas on your face.
