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:

  • Informed consent is a legal document that explains the tests, treatments, or procedures that you may need. Informed consent means you understand what will be done and can make decisions about what you want. You give your permission when you sign the consent form. You can have someone sign this form for you if you are not able to sign it. You have the right to understand your medical care in words you know. Before you sign the consent form, understand the risks and benefits of what will be done. Make sure all your questions are answered.
  • An IV is a small tube placed in your vein that is used to give you medicine or liquids.
  • Anesthesia:
    • General anesthesia will keep you asleep and free from pain during surgery. Anesthesia may be given through your IV. You may instead breathe it in through a mask or a tube placed down your throat. The tube may cause you to have a sore throat when you wake up.
    • Regional anesthesia: Medicine is injected to numb the body area where the surgery or procedure will be done. You will remain awake during the surgery or procedure.

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. 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 problems, you may be able to go home. If you are staying in the hospital, you will be taken to your hospital room.

  • A Foley catheter is a tube put into your bladder to drain urine into a bag. Keep the bag below your waist. This will prevent urine from flowing back into your bladder and causing an infection or other problems. Also, keep the tube free of kinks so the urine will drain properly. Do not pull on the catheter. This can cause pain and bleeding, and may cause the catheter to come out.
  • Medicines:
    • Antibiotics: Antibiotics may be given to help prevent an infection caused by bacteria.
    • Pain medicine: You may be given a prescription medicine to decrease pain. Do not wait until the pain is severe before you ask for more medicine.


  • 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.
