A cone biopsy is an outpatient surgical procedure that is used to remove suspicious tissue from deep within the cervical canal for further analysis under a microscope after a Pap test has come back with abnormal results. It is called a “cone” biopsy due to the wedged shape of the tissue sample that is obtained, which will also include a small margin of normal tissue. To minimize discomfort during the procedure, the patient may receive either general, regional or local anesthesia (cervical block) along with IV or oral pain medications. One method of extracting the suspicious cells is called the LEEP procedure (short for Loop Electrosurgical Excision), which employs a thin wire through which an electric current is passed in order to slice away a thin layer of tissue. Most women experience some bleeding for up to one week following a cone biopsy, plus spotting or discharge for up to another two weeks.
