Moles can be easily removed. Using local anesthetic, the mole is removed either with a shave technique (which requires no stitches) or a deeper excision requiring stitches. If a mole appears to be completely harmless, sometimes it can just be burned off. Scars are expected but are made as minimal as possible. Most moles do not need to be removed, but if they are changing, atypical in appearance, irritated by clothing, or aesthetically undesirable, they can removed. Pathology is sometimes required and if there is any concern about the mole after it is analyzed, more surgery may be needed.
