Mohs surgery is especially important in the treatment of skin cancers that have already recurred after previous treatment, or, have a high risk of recurring. While this particular cancer surgery is not necessarily appropriate for all types of skin cancers, it is especially useful when it is necessary to save as much healthy tissue as possible for functional or cosmetic purposes. Skin cancers located in such areas as the ears, nose, lips, hairline, eyelids, genitals, feet, and hands benefit the most from Mohs surgery.
