LEEP or loop electrosurgical excision procedure is an in-office technique for removing abnormal cervical cells that are suspected of being or becoming cancer. It requires only local anesthesia, takes just a few minutes to perform, and removes more tissue than a cervical biopsy. LEEP is also a diagnostic tool since the cells that are removed are sent to a pathology lab for analysis. The patient experiences no discomfort during the procedure and possible mild cramping afterwards. The cervix heals in about four weeks.
