Basal Cell Carcinoma

Basal cell carcinoma (BCC) is the most common form of skin cancer, affecting approximately one million Americans each year. In fact, it is the most common of all cancers. More than one out of every three new cancers are skin cancers, and the vast majority are basal cell carcinomas. These cancers arise in the basal cells, which line the deepest layer of the epidermis (top skin layer).

Almost all basal cell carcinomas occur on parts of the body excessively exposed to the sun — especially the face, ears, neck, scalp, shoulders, and back. On rare occasions, however, tumors develop on unexposed areas. In a few cases, contact with arsenic, exposure to radiation, open sores that resist healing, chronic inflammatory skin conditions, and complications of burns, scars, infections, vaccinations, or even tattoos are contributing factors.

Basal cell carcinomas are easily treated in their early stages. The larger the tumor has grown, however, the more extensive the treatment needed. Although this skin cancer seldom spreads, or metastasizes, to vital organs, it can damage surrounding tissue, sometimes causing considerable destruction and disfigurement — and some basal cell carcinomas are more aggressive than others.
