Basal-cell carcinoma or basal-cell cancer (BCC), a skin cancer, is one of the most common cancers in the United States. It rarely metastasizes or kills. However, because it can cause significant destruction and disfigurement by invading surrounding tissues, it is still considered malignant.Statistically, in the United States approximately 3 out of 10 Caucasians may develop a basal-cell cancer within their lifetime. In 80 percent of all cases, basal-cell cancers are found on the head and neck. There appears to be an increase in the incidence of basal-cell cancer of the trunk in recent years.
