A shave excision is typically the easiest and most cost effective way of removing the majority of moles on the legs. It will also give the best chance of minimizing the scar. With this method the mole is actually "shaved off" at a level just below the surface of the skin. The tissue that has been removed can then be sent for microscopic examination to make sure the mole is benign. Dermatologic surgeons are experts at doing this procedure.
