Curettage is the process of scraping skin with a spoon-shaped tool (curette) to remove skin tissue. Electrosurgery is the burning of skin tissue with an electric current that runs through a metal tool or needle. It may be done after curettage to control bleeding and destroy any remaining cancer cells. The wound is then covered with an antibiotic dressing.
The skin is numbed with a local anesthetic before the procedure. Curettage and electrosurgery may be repeated once or twice. Or they may be combined with other procedures, such as cryosurgery.
Recovery may take 3 to 6 weeks, depending on the extent of surgery. Keep the wound clean and dry. A scab will form over the area.
Curettage and electrosurgery are done to:
Treatment with curettage and electrosurgery for skin cancer has a cure rate of nearly 99 out of 100 for basal cell cancer that is less than 1 cm (0.5 in.) wide. The cure rate is about 84 out of 100 if the cancer is larger than 2 cm (1 in.) wide.footnote 1 This procedure works best on new skin cancers. It is less successful for recurrent skin cancers where scar tissue has developed.
Risks of using curettage and electrosurgery for skin cancer include:
