There are various methods employed in Skin/Laser Surgery. Besides removing skin lesions by cutting with a surgical knife, other methods used include: cryosurgery,electrosurgery and laser surgery. In cryosurgery, a cold substance (usually liquid nitrogen) is used to destroy the skin growth by a freezing process.
In electrosurgery, various forms of controlled electric currents are employed to destroy tissue.
In laser surgery, a precise and intense light beam is used to burn and destroy tissue. All of the above methods are usually performed under local anaesthesia, in some cases, no anaesthesia is required at all. Usually such surgical procedure will take less than 30 minutes to perform. The patient will usually be able to return home immediately after surgery and often, be able to resume work in a day or two.
