Definition of conization


A procedure in which a cone-shaped piece of abnormal tissue is removed from the cervix. A scalpel, a laser knife, or a thin wire loop heated by an electric current may be used to remove the tissue. The tissue is then checked under a microscope for signs of disease. Conization may be used to check for cervical cancer or to treat certain cervical conditions. Types of conization are LEEP (loop electrosurgical excision procedure) and cold knife conization (cold knife cone biopsy). Also called cone biopsy.
