You may be a little nervous when you hear from a doctor that you're going to have a "Cone Biopsy." When we hear the word "biopsy," we immediately think of something serious. But, in reality, this is a very important test and treatment that is often done for your own good. So, let's talk about it in a few details. In a way that you can understand, simply.
What is a Cone Biopsy?
Simply put, a cone biopsy is a minor procedure in which a small piece of tissue is removed from your cervix in a cone-shaped manner. This is sometimes called a conization. Think of it like baking a cake and cutting a small piece from the inside to see how it looks. That's how it works.
Your cervix is the part of your body where the upper part of your vagina meets the lower part of your uterus. This cone biopsy can examine not only the surface of your cervix, but also cells that are a little deeper down. The tissue removed in this way is sent to a lab to be examined to see if there are any abnormal cells, cancer cells, or changes in cells that could lead to cancer (cervical dysplasia).
This is an outpatient procedure, usually performed in a hospital or operating room.
Why is a cone biopsy performed?
Most often, a doctor will suggest performing a cone biopsy for the following reasons:
- If your Pap smear results show that there are any abnormal changes in the cells of your cervix , these changes may be a precursor to cancer.
- If you need to remove abnormal, cancerous, or precancerous cells from the cervix.
- If you have very early cervical cancer (stage 0 or IA1), removing this area of cells is a treatment .
Sometimes, if a previous ``(Colposcopy)`` (examination of the cervix with a camera) or ``(Punch Biopsy)`` (taking a small piece of tissue) cannot pinpoint the cause of these cell changes, a cone biopsy may be performed as the next step.
Important: This not only removes abnormal cells, but also identifies exactly what those cells are and what their nature is. This means it is important both as a diagnosis and as a treatment .
Who performs this cone biopsy?
This surgery is performed by an Obstetrician-Gynecologist (Ob/Gyn) who has extensive experience in this area.
How do we prepare for this?
Your doctor will give you instructions on how to prepare for this. Most often, this is done under general anesthesia (meaning you are completely asleep), so you will be asked to stop eating and drinking for a few hours before the procedure. You may also be advised to avoid sexual intercourse and not insert anything into your vagina in the days before the procedure.
Are we awake during a cone biopsy?
Usually not. Most of the time, you will be given general anesthesia for this procedure. However, very rarely, your doctor may suggest a local anesthetic ( such as a nerve block) that numbs only the area below the waist. However, you will not feel any pain during this procedure.
What happens during surgery? Don't worry, this is what happens!
A cone biopsy involves using a scalpel to cut a cone-shaped piece of abnormal tissue from the cervix. The tissue is then sent to a laboratory, where a pathologist (a doctor who specializes in examining tissue) looks at it under a microscope to see if it contains cancer or precancerous cells.
The surgery itself takes about 15 minutes, but the preparation before and the recovery after the surgery can take several hours.
Here's what happens in order:
1. Anesthesia: First, you will be anesthetized.
2. Positioning: Then, you will be placed in the position you would be in for a Pap smear, with your legs on the appropriate supports.
3. Inserting the Speculum: Next, the doctor will insert a device called a speculum into your vagina. This will spread the walls of your vagina apart and allow you to see your cervix clearly.
4. Colposcope: Next, a device called a colposcope, which has a light and magnifying lens, is inserted into the vagina to examine the cervix. This is used to check the exact area to be removed.
5. Removing the tissue section: Next, the surgeon removes the abnormal tissue section, along with some of the normal tissue around it, in a cone shape.
6. Stopping the bleeding: Then, various methods are used to stop the bleeding. Sometimes stitches may be placed, or ``Cauterization`` (cauterizing the blood vessel with electricity or heat) . Sometimes you may also place something like gauze inside the vagina to stop the bleeding.
The pathologist examines the removed tissue to see if the surgeon removed all the abnormal tissue or if only normal tissue is left.
As mentioned earlier, this is a same-day surgery. Once you are well enough to recover, you will be sent home from the hospital or surgery center.
What to expect after a cone biopsy?
You will be monitored in the hospital or operating room for a few hours after the surgery. Your blood pressure, pulse, bleeding, and pain will be checked, and you will be discharged home when you are well enough to go home. If you have any gauze in your vagina, it will be removed before you go home.
- Pain: You may experience cramping in your lower abdomen for a few days, similar to menstrual cramps. You can take painkillers for this. Your doctor may prescribe painkillers, or you can often control this pain with over-the-counter pain relievers from the pharmacy.
- Daily chores: You should be able to resume normal activities in about a week. However, it's a good idea to ask friends and family for help with heavy household chores (like vacuuming and laundry) during the first week.
- Blood and discharge: During this time, it is normal to experience some vaginal bleeding and discharge along with lower abdominal pain. Use sanitary pads for this. It is also normal for this discharge to be red or pink at first, then turn light brown.
Your doctor will give you a list of things you should not do until your next follow-up appointment. These may include:
- Do not insert anything into the vagina for about four weeks. This means no sexual intercourse, using tampons, inserting fingers, or douching.
- Avoid lifting weights or doing strenuous exercises.
- Do not bathe in water (swimming, bathing in the bathtub).
Your doctor will schedule a follow-up appointment four to six weeks after your surgery to make sure everything went well and that the wounds are healing well.
After a cone biopsy, you may be asked to have a Pap test every six months. After several Pap tests come back normal, you will be returned to a regular Pap test schedule (e.g., once a year). This schedule may vary depending on your age and health history.
Are there stitches after a cone biopsy?
Sometimes. Your surgeon may use stitches, but most often they will use a vaginal packing. This is something like a tampon or a large rolled piece of gauze.
Can I go back to work after a cone biopsy?
You can return to work in a few days, when you feel comfortable. However, if your job requires heavy lifting or hours of standing, you may need to stay home for about two weeks.
What are the risks of this cone biopsy?
A cone biopsy is generally a safe procedure , but like any surgery, it can have some risks. Talk to your doctor about the risks and benefits of this procedure so you have a clear understanding of what to expect.
Some of the risk situations are:
- Bleeding
- Blood Clots
- Infection
- Cervical Stenosis
- Increased risk of preterm labor in future pregnancies
- Damage to nearby organs such as the bladder or rectum
A cone biopsy can cause scarring of the cervix, which may make it more difficult for the doctor to detect abnormal cells in future Pap tests.
What are the side effects of Cone Biopsy?
The most commonly seen side effects are:
- Menstrual-like cramping
- Discomfort or slight pain
- Vaginal bleeding or spotting
These side effects may be more severe in the first week after surgery, but they will gradually decrease over time. If you still have moderate to severe pain and bleeding after two weeks, see your doctor immediately.
Can a cone biopsy remove cancer?
Yes, this cone biopsy can remove cancer cells in the very early stages of cervical cancer.
When do I get the results of a cone biopsy?
Your doctor should receive the biopsy results within about a week. However, this time frame can vary depending on the lab. It's best to ask your doctor how long it will take to get the results.
What do the results of a cone biopsy tell us?
The tissue sample taken from your cervix is analyzed under a microscope in a laboratory. Your test results will help your doctor determine whether the cells are normal, precancerous, or cancerous.
- A normal result means that no pre-cancerous or cancerous cells were found in your cervix.
- An abnormal result means that precancerous or cancerous cells have been found on your cervix. These cells are called Cervical Intraepithelial Neoplasia (CIN) . CIN is graded from 1 to 3, depending on how much of the cervical tissue contains these abnormal cells.
- CIN I: Mild cervical dysplasia. There is a slight abnormality in the cells.
- CIN II: Moderate to marked cervical dysplasia. The cells are abnormal.
- CIN III: Severe cervical dysplasia or carcinoma in situ. The cells are very abnormal and have a high chance of becoming cancerous.
CIN I rarely becomes cancerous. CIN II and CIN III are more likely to require treatment to prevent cancer.
When should I see my doctor?
If you experience any of the following symptoms , see your doctor immediately :
- Fever (101°F or higher)
- Feeling cold and shivering, having difficulty breathing, feeling dizzy
- Swelling in the legs or painful leg cramps (these could be a sign of a blood clot)
- Bleeding enough to change a sanitary pad every two hours
- If the pain doesn't subside after taking medicine
- Vaginal discharge with a foul odor
What is the difference between Cone Biopsy and LEEP?
Conization / Cone Biopsy and LEEP (Loop Electrosurgical Excision Procedure) are both methods used to remove abnormal tissue from the cervix.
- LEEP uses a small, electrically charged wire loop to cut and remove abnormal tissue.
- A cone biopsy involves using a surgical knife to cut a cone-shaped piece of tissue from the cervix, which is larger than a laparotomy. A cone biopsy is a slightly more complicated procedure than a laparotomy, and it is performed under general anesthesia. The recovery time is longer and the risks are slightly higher than a laparotomy.
How many times can a cone biopsy be done?
Sometimes, if abnormal cells remain at the edges of the removed tissue, or if new abnormal cells develop, another cone biopsy or other treatment may be needed. Depending on your test results, your doctor will discuss the risks and benefits of having another cone biopsy with you.
Final Take-Home Message
Cone biopsy is an important procedure that can help identify and treat abnormal cells that could lead to cervical cancer. It's normal to feel nervous and scared before this procedure. Get support from your family, friends, and your medical team. Don't hesitate to ask any questions you have about the procedure or your results.
Most of the time, cone biopsy is successful, and there are no long-term side effects. The best way to detect abnormal cells on your cervix early is to continue getting Pap smears. So be sure to take care of that too.
