Cone biopsy for cervical cancer detection and treatment

What is Cone Biopsy?

cone biopsyCone biopsy, also known as cervical conization, is a surgical procedure where a cone-shaped tissue sample is removed from the cervix and examined under the microscope. It is a more extensive form of cervical biopsy which is usually done when a Pap test indicates moderate to severe cell changes.

Purpose of cone biopsy

You may be advised by your doctor to have a cone biopsy for to the following reasons:

  • When abnormal tissue collected in a cervical biopsy cannot be seen through colposcopy
  • When abnormal tissue seen in colposcopy extends high into the cervical canal
  • As a diagnostic procedure to determine the length, severity, and extent of cancerous cells when cervical cancer is suspected based on Pap tests, cervical biopsy, and colposcopy
  • To examine abnormal cell changes and remove them at the same time
  • Treatment of very early stage cervical cancer

Preparation for cone biopsy

Commonly, you may be given a general anesthesic so that you will be unconscious during the procedure. Regional anesthesia may also be given during cone biopsy, which will numb the entire genital area. When using the Loop Electrical Excision Procedure (LEEP), cone biopsy may be done under cervical block (anesthetic procedure that numbs the cervix) together with intravenous pain medications. To avoid risks involved with anesthesia, you will be asked to take nothing by mouth after midnight on the day of the operation.

Cone biopsy is usually done on an outpatient basis. You can expect to be discharged a few hours after the procedure. An overnight stay in hospital is usually not necessary.
