ED&C stands for electrodessication and curettage. This procedure is mostly used on patients who have non-melanoma skin cancers in non-crucial areas where a small scar would be less noticeable.
First a small injection of local anesthetic is placed. The surgeon then uses a curette to remove the abnormal cells by scraping down to a layer of uninvolved tissue. Finally, desiccation (electrosurgery) is performed with a hyfrecator to widen the margin and cauterize the wound to minimize bleeding. The wound is left to heal without sutures and typically heals over several weeks.
