Common moles do not need to be removed. However, some people choose to have them removed for cosmetic reasons; if they are raised and located in areas where clothing irritates them, such as the waistline; or if they are on the scalp and are irritated by hair brushing. Most moles can be cut off in a simple in-office procedure. Moles and dysplastic nevi whose appearance suggests they may be cancerous should be removed and examined under a microscope. If they are found to be cancerous, additional skin in the surrounding area also must be removed.
