Also called loop electrosurgical excision procedure (LEEP), this is the most common way of treating precancerous changes of the cervix. The abnormal tissue is removed using a thin wire loop that is heated electrically.

The aim is to remove all the abnormal cells from the surface of the cervix and it's done under local anaesthetic in your doctor’s clinic or under local or general anaesthetic in hospital. A LLETZ takes about 5–10 minutes and results are usually available in 1–2 weeks.

You may have some vaginal bleeding and cramping after the procedure. These side effects will usually ease in a few days, but you may notice some spotting for several weeks.

If the bleeding lasts longer than 3–4 weeks, becomes heavy, has an unpleasant smell or you develop fever or intense pelvic pain, see your doctor.

You should not have sexual intercourse or use tampons for 4–6 weeks after the procedure. You will also need to avoid baths, swimming pools and spas.

After a LLETZ or LEEP you can still become pregnant, but you may have a slightly higher risk of having the baby prematurely. Talk to your doctor before the procedure if you are concerned. 

This procedure is used when abnormal cells are found in the cervical canal, if a larger area needs to be removed or when early-stage cancer is suspected.

In some cases, a cone biopsy is also used to treat very early-stage cancers, particularly if you would like to have children in the future.

A cone biopsy is usually done as day surgery in hospital under general anaesthetic. A surgical knife (scalpel) is used to remove a cone-shaped piece of tissue from the cervix, which is examined to make sure all the abnormal cells have been removed.

Results are usually available within a week. After a cone biopsy, you may have some light bleeding or cramping for a few days. Avoid doing any heavy lifting for a few weeks.

If the bleeding lasts longer than 3–4 weeks, becomes heavy, has an unpleasant smell, or you develop a fever or intense pelvic pain, see your doctor.

You may notice a dark brown discharge for a few weeks, but this will pass. You should not have sexual intercourse or use tampons for 4–6 weeks.

A cone biopsy may weaken the cervix. You can still become pregnant after a cone biopsy, but you may be at a higher risk of having a miscarriage or having the baby prematurely.

If you would like to become pregnant in the future, talk to your doctor before the procedure. 

This procedure uses a laser beam (a strong, hot beam of light) to destroy or remove the abnormal cells. The laser beam is pointed at the cervix through the vagina.

Laser surgery is done under either local or general anaesthetic. It takes about 5–10 minutes, and you can go home after the treatment when you have recovered from the anaesthetic.

Laser surgery works just as well as LLETZ to remove precancerous cells and can be a better option if the precancerous cells extend from the cervix into the vagina or if the lesion on the cervix is very large.

Side effects of laser surgery are similar to those of LLETZ. You are usually able to return to your usual activities after 2–3 days, but you should not have sexual intercourse or use tampons for 4–6 weeks. You will also need to avoid baths, swimming pools and spas. 

You may have a blood test to check your general health, and how well your kidneys and liver are working. 

You may have one or more of the following imaging scans to find out if the cancer has spread to lymph nodes in the pelvis or abdomen, or to other organs in the body:

CT scan

Uses x-rays to take pictures of the inside of your body and then compiles them into a detailed, three-dimensional picture. It is painless and takes 5–10 minutes.

MRI scan

Uses a powerful magnet and radio waves to create detailed cross-sectional pictures of the inside of your body. It is painless and takes between 30 and 90 minutes. Let your medical team know if you have a pacemaker or any other metal implant, as some may affect how an MRI works. 

PET–CT scan

A specialised imaging test that provides more detailed information about the cancer than a CT scan on its own. Not all people need to have a PET–CT scan.

You will be injected with a glucose (sugar) solution containing a small amount of radioactive material to help cancer cells show up brighter. Let your doctor know if you are claustrophobic, as you need to be in a confined space for the scan.

It may take a few hours to prepare, but the scan itself usually takes about 30 minutes.

Another way to check whether the cancer has spread is for the doctor to examine your cervix, vagina, uterus, bladder and rectum. This is done in hospital under general anaesthetic.

If the doctor sees any abnormal areas of tissue during the procedure, they will usually take a biopsy. The area examined will depend on where the cancer may have spread to and may include:

• Pelvic examination – the doctor will put a speculum into your vagina and spread the walls of the vagina apart so they can check the cervix and vagina for cancer.
• Uterus – the cervix will be dilated (gently opened) and some of the cells in the lining of the uterus (endometrium) will be removed and sent to a laboratory for examination. This is called a dilation and curettage (D&C).
• Bladder – a thin viewing instrument with a camera and light on the end (a cystoscope) will be inserted into your urethra (the tube that drains urine from the bladder). This lets the doctor examine your bladder.
• Rectum – the doctor will use a gloved finger to feel for any abnormal growths inside your rectum. To examine your rectum more closely, the doctor may insert an instrument called a sigmoidoscope, which is a tube with an attached camera.

For people who will be having radiation therapy, the doctor may implant small markers into the cervix or vagina to show the size and position of the cancer.

The markers (called fiducials) are made of gold and are about the size of a grain of rice. They can be seen on x-ray and CT scans and are used to guide radiation therapy treatment.

You will most likely be able to go home from hospital on the same day after one of these examinations. You may have some light bleeding and cramping for a few days afterwards. Your doctor will talk to you about the side effects you may have.
