A cone biopsy is an extended form of a cervical biopsy. It is called a cone biopsy because a cone-shaped wedge of tissue is removed from the cervix and examined under a microscope. A cone biopsy removes abnormal tissue that is high in the cervical canal. A small amount of healthy tissue around the cone-shaped wedge of abnormal tissue is also removed so that a margin free of abnormal cells is left in the cervix.
A cone biopsy can:
• Remove a thin or a thick cone of tissue from the cervix, depending on how much tissue needs to be examined.
• Be used to diagnose and sometimes to treat abnormal cervical tissue. The abnormal tissue is removed and sent to a lab to be tested.
A sample of tissue can be removed for a cone biopsy using:
• A surgical knife (scalpel).
• A carbon dioxide (CO2) laser.
• Loop electrosurgical excision procedure (LEEP).
A cone biopsy is usually done as an outpatient procedure. You do not have to spend a night in the hospital.
The hospital or surgery center may send you instructions on how to get ready for your surgery. Or a nurse may call you with instructions before your surgery.
You will need to take off your clothes below the waist and drape a paper or cloth covering around your waist. You will lie on your back on an exam table with your feet raised and supported by footrests (stirrups). Your doctor will insert a lubricated tool called a speculum into your vagina. The speculum gently spreads apart the vaginal walls, allowing the inside of the vagina and the cervix to be examined.
Medicine that makes you unconscious (general anesthesia) or that makes the entire genital area numb (regional anesthesia, such as a spinal or epidural) may be used.
A cone biopsy using LEEP may be done in your doctor’s office with an injected medicine that numbs the cervix (cervical block). If a cervical block is used, oral pain medicine or pain medicine is given into a vein (intravenous, or IV) may be used along with the local anesthetic.
Right after surgery, you will be taken to a recovery area where nurses will care for and observe you. You likely will stay in the recovery area for 1 to 4 hours, and then you will go home. In addition to any special instructions from your doctor, your nurse will explain information to help you in your recovery. You will likely go home with a sheet of care instructions that include who to contact if a problem comes up.
Most women can return to their average activity level in 1 week.
If you have a cone biopsy, you need regular follow-up Pap tests and colposcopy examinations. A Pap test should be repeated every 4 to 6 months or as recommended by your doctor. After several Pap test results are normal, you and your doctor can decide how often to schedule future Pap tests.
