Cone Biopsy: Before Your Surgery

What is a cone biopsy?

A cone biopsy (conization) is a type of surgery. It removes a cone-shaped piece of tissue from the cervix. The cervix is the lower part of your uterus. It opens into your vagina.

There are a few ways the doctor can remove the tissue. One way is to use a surgical knife called a scalpel. Another way is to use a thin wire loop that's charged with electricity. Or the doctor can use a laser.

You may be asleep during the surgery. But it is usually done while you are awake. Either way, you will not feel pain. The doctor removes the tissue through the vagina. The surgery won't leave a scar on the outside of your body.

After surgery, another doctor will look at the tissue under a microscope. The doctor will check it for abnormal cells.

Most people go home 1 to 4 hours after surgery. You will probably be able to return to your normal routine in 1 or 2 days. But be sure to wait to have sex until your doctor says it's okay.

How do you prepare for surgery?

Surgery can be stressful. This information will help you understand what you can expect. And it will help you safely prepare for surgery.

Preparing for surgery

  • Do not douche, use tampons, or have sex during the 24 hours before surgery.
  • Be sure you have someone to take you home. Anesthesia and pain medicine will make it unsafe for you to drive or get home on your own.
  • Understand exactly what procedure is planned, along with the risks, benefits, and other options.
  • Tell your doctor ALL the medicines and natural health products you take. Some may increase the risk of problems during your procedure. Your doctor will tell you if you should stop taking any of them before the procedure and how soon to do it.
  • If you take aspirin or some other blood thinner, ask your doctor if you should stop taking it before your procedure. Make sure that you understand exactly what your doctor wants you to do. These medicines increase the risk of bleeding.
  • Make sure your doctor and the hospital have a copy of your advance care plan. If you don't have one, you may want to prepare one. It lets others know your health care wishes. It's a good thing to have before any type of surgery or procedure.

What happens on the day of surgery?

  • Follow the instructions exactly about when to stop eating and drinking. If you don't, your surgery may be cancelled. If your doctor told you to take your medicines on the day of surgery, take them with only a sip of water.
  • Take a bath or shower before you come in for your surgery. Do not apply lotions, perfumes, deodorants, or nail polish.
  • Do not shave the surgical site yourself.
  • Take off all jewellery and piercings. And take out contact lenses, if you wear them.

At the hospital or surgery centre

  • Bring a picture ID.
  • You will be kept comfortable and safe by your anesthesia provider. The anesthesia may make you sleep. Or it may just numb the area being worked on.
  • The surgery will take about 1 hour.

When should you call your doctor?

  • You have questions or concerns.
  • You don't understand how to prepare for your surgery.
  • You become ill before the surgery (such as fever, flu, or a cold).
  • You need to reschedule or have changed your mind about having the surgery.
