The treatment varies with the tumor's size, depth, location and how much it has spread (metastasis).
Surgical removal of the tumor, which may include removal of the skin around the tumor (wide excision), is often recommended. Microscopic shaving (Mohs' surgery) may remove small tumors. Skin grafting may be needed if wide areas of skin are removed.
The tumor may be reduced in size by radiation treatments. Chemotherapy can be used if surgery and radiation fail, but it is usually minimally effective.
