Electrocauterization is the process of destroying tissue using heat conduction from a metal probe heated by electric current. The procedure is used to stop bleeding from small vessels (larger vessels being ligated) or for cutting through soft tissue. Unlike electrocautery, electrosurgery is based on generation of heat inside tissue, using electric current passing through the tissue itself, and when used to stop bleeding, is technically referred to as electrocoagulation. Electrosurgery techniques are used in the treatment of skin cancers via electrodesiccation and curettage.
