Cervical Cone Biopsy


A cervical cone biopsy is surgery to remove abnormal cells from your cervix. The cervix is the opening into your uterus. Once the cells are removed, they are sent to a lab to be tested for cancer.


Before your surgery:

  • Ask your healthcare provider if you need to stop using aspirin or any other prescribed or over-the-counter medicine before your procedure or surgery.
  • Bring your medicine bottles or a list of your medicines when you see your healthcare provider. Tell your provider if you are allergic to any medicine. Tell your provider if you use any herbs, food supplements, or over-the-counter medicine.
  • Tell your healthcare provider if you know or think you might be pregnant.
  • Your healthcare provider may do a pelvic exam to check your vagina, cervix, and uterus. You may need blood tests or other tests to check for a sexually transmitted infection (STI), such as chlamydia or HPV. You may need a colposcopy, a CT scan, or an MRI. Talk with your healthcare provider about these or other tests you may need. Write down the date, time, and location for each test.
  • Write down the correct date, time, and location of your procedure.

The night before your surgery:

Ask healthcare providers about directions for eating and drinking.

The day of your surgery:

  • You or a close family member will be asked to sign a legal document called a consent form. It gives healthcare providers permission to do the procedure or surgery. It also explains the problems that may happen, and your choices. Make sure all your questions are answered before you sign this form.
  • Ask your healthcare provider before taking any medicine on the day of your procedure. These medicines include insulin, diabetic pills, high blood pressure pills, or heart pills. Bring a list of all the medicines you take, or your pill bottles, with you to the hospital.
  • Healthcare providers may insert an intravenous tube (IV) into your vein. A vein in the arm is usually chosen. Through the IV tube, you may be given liquids and medicine.
  • An anesthesiologist will talk to you before your surgery. You may need medicine to keep you asleep or numb an area of your body during surgery. Tell healthcare providers if you or anyone in your family has had a problem with anesthesia in the past.


What will happen:

  • You will be given anesthesia medicine that will keep you comfortable and free from pain during your surgery. Your healthcare provider will insert a speculum into your vagina. This is the same tool used during a pap smear. The speculum allows your healthcare provider to see inside your vagina to your cervix. Stitches may be put in your cervix to hold the cervix in place during the surgery. You may be given a shot of medicine into your cervix to help decrease bleeding. An incision will be made in your cervix to remove a cone-shaped piece of tissue. Your healthcare provider may also use an electrical wire loop to remove the tissue from your cervix.
  • Your healthcare provider will close the incision with stitches. Gauze with a liquid to prevent bleeding may be inserted into your vagina. A catheter (long, bendable tube) may be inserted into your bladder to drain your urine into a bag. The cone-shaped tissue removed from your cervix will be sent to a lab to be tested for cancer.

After your surgery:

You will be taken to a room to rest until you are awake. Do not get out of bed until your healthcare provider says it is okay. When healthcare providers see that you are not having any problems, you may be able to go home. If you are staying in the hospital, you will be taken to your hospital room.


  • You cannot make it to your surgery on time.
  • You have a fever.

Seek Care Immediately if

  • You have new or increased vaginal bleeding that is not from your monthly period.


  • You may bleed more than expected during or after your surgery. You may have a fever. You may get an infection in the wound or urinary tract. You may have pain in your lower abdomen. After a cervical cone biopsy, you may have difficulty getting pregnant. You may have a baby who is small or born too early. Your cervix may narrow, making it hard to find problems in the future. After your cervical cone biopsy, you may still have some abnormal cells, or abnormal cells may return. If abnormal cells return, you may need surgery to remove your uterus.
  • If you do not have a cervical cone biopsy, your condition could get worse. If you have an infection, it may spread to other areas in your body. Abnormal bleeding may get worse. Abnormal cells may turn into cancer, and the cancer may spread to other areas in your body.
