LEEP is a procedure used to remove abnormal cervical cells when a pap smear shows pre-cancerous changes, as it uses an electrified wire loop to precisely cut and remove the problematic tissue from the cervix. It is performed in a doctor's office under local anesthesia, allowing them to access and treat precancerous lesions before they have the chance to become cancerous. LEEP aims to eliminate the abnormal cells while preserving the ability to carry a pregnancy in the future.
