MOHS micrographic surgery is usually used if it is anticipated that the cancer may return or spread, or if it is in an awkward place where little skin can be removed. In this type of surgery, very little tissue is removed at any one time and each one is examined under a microscope for cancer. This procedure may have to be repeated several times, but the advantage is that as little healthy tissue is removed as possible. For this reason this procedure will give better cosmetic results.
