Scraping or burning-off skin growths (also known as electrodesiccation and curettage) can be used for less serious skin cancers, pre-cancers and benign growths. A local anesthetic is injected, and then the abnormal tissue is scraped off with a special tool. The area is then cauterized until bleeding stops. This may be repeated if the growth is cancerous. The wound will need to be dressed until it heals, and it usually leaves a small white mark.
