Electrosurgery is the procedure wherein electric current is being utilized in cutting, removing, or even destroying tissue as well as controlling bleeding. This is one of the most promising procedures in oncology. Electrosurgery has two types: high-frequency electrosurgery and electrocautery. With high-frequency electrosurgery, this type of electrosurgery refers to electrocoagulation, electrofulguration, and electrosection. All of those aforementioned methods deal with a high-frequency alternating current that is then converted to heat as it passes through the targeted tissue. On the other hand, electrocautery is more of transferring directly the heat to the targeted tissue. Electrosurgery is commonly used in treating mouth and skin cancers and even uterus tumor.
