Loop electrosurgical excision procedure (LEEP) is used to treat abnormal cells found on the surface of the cervix. During the procedure, the abnormal cells are removed to prevent development of cervical cancer.

Wire loops attached to an electrosurgical generator cut away the affected tissue, causing the cells to heat and burst. The tissue removed is sent to a lab for further evaluation, including ensuring that the abnormal area has been fully removed. An assessment as to the cause of the growth of abnormal tissue will also be done. The LEEP procedure takes 20-30 minutes and can be performed in the office. A local anesthetic is administered to minimize pain.
