If additional treatment is needed, options may include:
Freezing: Some small, early skin cancers are destroyed by freezing them with liquid nitrogen (cryosurgery).
Excisional surgery: The cancerous tissue and a surrounding margin of healthy skin is cut out.
Mohs surgery: This procedure is for larger, recurring or difficult-to-treat skin cancers. It's often used in areas where it's necessary to conserve as much skin as possible, such as the nose. The skin growth is removed layer by layer, until no abnormal cells remain. This procedure allows cancerous cells to be removed without taking an excessive amount of surrounding healthy skin.
Radiation therapy: High-powered energy beams, such as X-rays, are used to kill cancer cells. Radiation therapy may be an option when cancer can't be completely removed during surgery.
Chemotherapy: Drugs are used to kill cancer cells. For cancers limited to the top layer of skin, creams or lotions containing anti-cancer agents may be applied directly.
Biological therapy: Biological therapy uses the body's immune system to kill cancer cells.
