Basal cell carcinoma (BCC) is a type of skin cancer that arises from the basal (innermost) layer of skin. It is usually caused by excessive exposure to ultraviolet light (in sunlight, for example) and most commonly develops on the face. Typically, the growth appears as a small, painless lump with a smooth surface and a pearl-like border.
The lump grows slowly and may become ulcerated.
Untreated, it may destroy surrounding tissue, but it rarely spreads to other parts of the body.
Treatment is by surgical removal, freezing, radiation therapy, anticancer creams, or light treatment.
With treatment, most people are cured, although occasionally the cancer may recur.
