In addition, biological therapy and photodynamic therapy are being studied. The choice of treatment depends on the location and extent of the cancer and the patient s overall health. Surgery Surgery is the most common treatment for skin cancer and is used in the treatment of about 90 percent of skin cancer cases. Cryosurgery involves freezing the tumor. Simple excision cuts the cancer from the skin along with some of the healthy tissue around it.
Micrographic surgery is removal of the cancer and as little normal tissue as possible.
During this surgery, the doctor removes the cancer and then uses a microscope to look at the cancerous area to make sure no cancer cells remain. Laser therapy uses a highly focused beam of light that destroys only the cancer cells. Surgery may leave a scar on the skin. Depending on the size of the cancer, skin may be taken from another part of the body and put on the area where the cancer was removed. This is called a skin graft .
