A mole removal procedure goes how deep to prevent regrowth?

Several millimeters: To completely remove a mole, one must cut into the skin as the mole may extend several millimeters below the surgace. This will require a stich. However, sometimes we only wish to remove the protion of the mole that sticks out and bothers the patient: in this case we can"shave" the lesion flat parallel to the surface of the skin.
