Large loop excision of the transformation zone (LLETZ) is a type of surgery that removes a small part of the cervix. It can be used treat cervical cell changes (abnormal cells) or early stage cervical cancer, as well as to diagnose cervical cancer.
This information is written for people having LLETZ for cervical cell changes or cervical cancer. We know that having surgery can be overwhelming, so we hope this page helps you feel prepared. If you need more support, remember that we are here for you in other ways too. You could give us a call on 0808 802 8000 or use one of our other support services.

The nature of gynaecological and obstetric care means that intimate examinations are often necessary. We understand that for some people, particularly those who may have anxiety or who have experienced trauma, physical abuse or sexual violence, such examinations can be very difficult. If you feel uncomfortable, anxious or distressed at any time before, during, or after an examination, please let your healthcare professionals know. If you find this difficult to talk about, you may communicate your feelings in writing.
Your healthcare professionals are there to help and they can offer alternative options and support for you. Remember that you can always ask them to stop at any time and that you are entitled to ask for a chaperone to be present. You can also ask to bring a friend or relative if you wish.
If you find intimate examinations difficult, we are here to support you. You can speak with our volunteers on 0808 802 8000 or you may prefer to contact us online.
Before you make a decision about treatment, it is important to understand the procedure, including benefits, risks and possible effects. Your colposcopist should explain these to you and give you the chance to ask any questions. You may also want to talk over your options with your family or friends.
It can help to write a list of questions and take it to your appointment. The form below suggests some questions you might like to ask and has space for you to write down any others you think of.
LLETZ is the most common treatment for cervical cell changes, but it can also be used to treat early stage cervical cancer. It uses a thin wire loop with an electrical current to remove the affected area of the cervix.
Your appointment will happen in a colposcopy clinic at a hospital. You usually have LLETZ as an outpatient. This means you have it in a hospital examination room, but can go home afterwards.
You usually have a local anaesthetic for LLETZ. But you can choose to have it done under general anaesthetic, where you are asleep. If you would prefer this, talk to your colposcopist about the risks and benefits before your appointment.
The hospital wants to keep you and their staff protected from COVID-19 (coronavirus), so they will be following government guidance on social distancing and using appropriate personal protective equipment (PPE), including masks, gloves and aprons. You will also need to wear a face covering while in the hospital.
If you take blood thinning medication or have a condition that affects your blood, it is important to tell your colposcopist before your appointment. You may have a higher risk of bleeding after the treatment.
You will have LLETZ lying on your back on an examination couch. The examination couch is adjustable and hoists are usually available if you need assistance.
Like during cervical screening, your colposcopist will gently put a clean speculum into your vagina. Speculums come in different sizes so, if you find the standard size uncomfortable or painful, you can ask for a smaller one.
Your colposcopist will inject a local anaesthetic into your cervix. This means you are awake, but the area that needs treating is numb (you can’t feel it). The injection might sting for a short time and you may be aware of your heart beating faster. This feeling should pass within a couple of minutes.
You may also have a sticky pad put onto on your leg. This makes sure the electric current in the wire loop doesn’t burn you.
Before starting the treatment, your colposcopist will touch your cervix to check it is numb.
Once your cervix is numb, your colposcopist uses the loop to remove the area of your cervix that has cancer cells. It is normal to notice a slight burning smell and hear a noise like a soft vacuum cleaner.
The loop cuts the tissue and then another small instrument is used to seal the cut. This should not be painful, but you may feel some pressure. The treatment usually takes less than 2 minutes.
The cells and tissue that has been removed is sent to a laboratory. They will test it to check whether:
This is done by testing for an ‘edge’ of healthy cells around the area that was removed. This is sometimes called having clear margins. They will also check what type of cervical cell changes or cervical cancer you had.
Once the anaesthetic has worn off, you may have some bleeding. Your colposcopist should offer you a period pad to use, but you might like to bring your own. Do not use tampons or menstrual cups that you put into your vagina.
You may have some physical effects after LLETZ. These usually last up to 4 weeks. Until these have stopped, it is best to avoid:
If you have any questions about what you can and can’t do after LLETZ, speak with your colposcopist.
Follow-up after LLETZ will depend on whether you had treatment for cell changes or cervical cancer. In this section, we talk about follow-up after LLETZ for cervical cancer. We have information about follow-up for cell changes on a different page.
After LLETZ for cervical cancer, you will be invited for follow-up appointments at your GP surgery or the colposcopy clinic. This should happen at both:
At this follow-up appointment, you will have a test of cure. This is like cervical screening, where a sample of cervical cells is tested for high-risk HPV.
If you have high-risk HPV at either appointment, you will be invited back to colposcopy for further tests. If you do not have high-risk HPV at either appointment, you will continue to be invited for follow-up appointments once a year for 9 years. After this, you will:
LLETZ is usually successful. The benefit of the treatment is that it can remove cervical cancer or prevent potential cervical cancer from developing which, in many cases, will outweigh the risks. However, like all treatments, LLETZ has risks and you may have some physical or emotional effects because of the treatment.
Talk to your colposcopist before treatment if you are worried about any risks. They can answer your questions and give you support. After treatment, your GP or a specialist doctor will be able to offer support.
About 85 in 100 (85%) people experience bleeding after LLETZ. About 15 in 100 (15%) people do not experience bleeding. Bleeding is expected after LLETZ and can last between 2 days to up to 4 weeks.
You may have bleeding because of the soft scab that forms on the cervix where the cells were removed. This may bleed while it heals.
The bleeding is usually like a period, but may be slightly heavier than your normal period. About 10 days after treatment, the bleeding may get heavier. This is common and a sign that the scab is healing. Your first period after treatment may be slightly heavier or out-of-sync with your regular cycle.
Important! If you are on blood thinning medication or you have a haematological condition, you must tell your colposcopist because you may have a higher risk of bleeding after LLETZ. If the bleeding is soaking through a period pad every hour, call the contact number given by your colposcopy team or call 111 out of hours. This is sometimes called delayed haemorrhaging. The hospital team or 111 will be able to advise you and make sure you get the right care.
About 67 in 100 (67%) people experience pain after LLETZ. About 33 in 100 (33%) people do not experience pain.
Some pain is expected for between 2 days to up to 4 weeks after treatment. The pain varies from person to person, but should not be too severe. It is often described as a cramping pain, like a period. You can talk to your doctor about over-the-counter medication that should help.
Important! Some people may experience pain for longer, but it usually goes away within 3 months. If you are in a lot of pain or find it is affecting your day-to-day life, talk to your GP. They can advise on pain medication, offer reassurance based on your medical history and, if needed, will be able to check you are healing properly.
About 65 in 100 (65%) people have changes to their vaginal discharge. About 35 in 100 (35%) people don’t have any changes to their vaginal discharge.
Changes to vaginal discharge can last for about 4 weeks. Straight after treatment, you may have a watery, brown vaginal discharge.
About 10 days after treatment, you may notice a coffee granule-like vaginal discharge. This is normal and a sign that the soft scab on your cervix is healing.
Important! Between about 1 and 14 in 100 (0.8% to 14%) people get an infection after LLETZ. Talk to your GP if your vaginal discharge smells bad, or is a yellow or green colour. If there is a chance you have an infection, you will be offered antibiotics.
About 2 in 100 (2%) people who become pregnant at any time after LLETZ will give birth before 37 weeks (prematurely) because of the treatment. About 98 in 100 (98%) people will not give birth prematurely because of the treatment.
Giving birth prematurely is more likely if you have had LLETZ more than once or had more than 10mm of your cervix removed. Most LLETZ treatments remove less than 10mm of your cervix.
If you become pregnant after LLETZ, tell your doctor or midwife that you have had the treatment. They may refer you to a specialist in preventing preterm birth.
The opening of the cervix (the os) can narrow or close and become scarred after LLETZ. This is called cervical stenosis. If this happens, the passage between the womb and vagina may become partly or fully blocked. Research suggests there is between a 2 to 14 in 100 (2% to 14%) risk of this happening.
You are more likely to develop cervical stenosis if you:
You may not have any symptoms of cervical stenosis. If you have periods, they might become irregular or painful. If you are trying to become pregnant, the sperm may not be able to get to the womb. It may also be harder for your doctor or nurse to do cervical screening in the future, but you can be referred to colposcopy if this happens.
Cervical stenosis can sometimes be treated with cervical dilators to help widen the cervix.
Jo’s Cervical Cancer Trust has spoken with women and people with a cervix who have had treatment for cervical cell changes to understand their experiences. In most cases, they had LLETZ for high-grade cell changes – CIN2 or CIN3. The figures in this section are taken from that research to help you feel as prepared as possible.
It is important to remember that everyone heals at a different pace and will have a different experience after LLETZ.
You may have strong feelings about what LLETZ means for your physical wellbeing and future. These feelings could be positive, such as relief that you have had treatment, but you may also feel worried about how your body will recover.
For the women and other people with a cervix that we spoke with:
All of your feelings and concerns, including any we don’t mention in this guide, are valid and it is important you get the right support to deal with them. Here are some of the ways you could get support.
Some people find that a support network of friends and family helps their emotional recovery after LLETZ. There are lots of ways they can help, from talking your feelings through, to offering a distraction and positive presence.
Before, during and after LLETZ, you will be in the care of professionals who want to make the experience as good as possible for you. If you are worried about anything, talk to them so they can give you the right support and ease any concerns. Or, if you have another doctor you know and trust, ask to talk with them about any worries.
There are many charities and organisations who offer support services so you can feel listened to and work through your feelings. These services can also signpost to other places that may be able to help.
If you feel that expert support would help, you can self-refer or ask your GP to make a referral for NHS counselling. You can also make an appointment privately, for a cost.
You may experience sex and intimacy differently after LLETZ. This may also have an impact on your relationships. These differences may be because of physical changes, emotional changes, or both.
In the women and other people with a cervix that we spoke with, about 46 in 100 (46%) had changes to how they feel, while 54 in 100 (56%) did not. These changes included feeling less attractive or confident, as well as worries about passing on HPV.
About 33 in 100 (33%) people had pain during or after sex, while 67 in 100 (67%) did not. In most cases, this pain lasted for less than 3 months. In some cases, pain during or after sex lasted for:
About 22 in 100 (22%) people had bleeding during or after sex, while 78 in 100 (78%) did not. In most cases, the bleeding lasted for less than 3 months. In some cases, the bleeding lasted for:
It is important to see your GP if you have any symptoms such as pain or bleeding. They can examine you and talk through ways to make it better, such as using more lubricant during sex to lessen any pain.
It may help to speak to a trusted person about any loss of confidence – whether that is a partner, family, friends, your GP, or other people who have had LLETZ. Talking through your worries might ease them or give you new ideas about how to handle them.
If you and a partner are struggling to reconnect after LLETZ, you may want to consider couples counselling. An unbiased expert can help you start and explore conversations around sex and intimacy, so you can find solutions together. You can self-refer through local NHS services, speak with your GP, or search for a local counsellor yourself.
Some pelvic pain is expected for a couple of days after LLETZ, but you may have pain for longer. We don’t know if this is directly because of the treatment or because of other conditions or life events that have happened since treatment.
In the women and people with a cervix that we spoke with, pelvic pain lasted for:
If you experience lasting pelvic pain, it is important to speak with a doctor. They can investigate the cause of the pain and offer the right support.
There is a small chance you may experience other effects after LLETZ. We spoke with a few women and people that had LLETZ who said their periods have permanently changed, cervical screening is more uncomfortable or they no longer feel the same sensations during sex. We don’t know if this is directly because of the treatment or other conditions or life events that have happened since treatment.
If you experience these effects, or anything we don’t mention on this page, speak with your doctor or nurse. They will be able to offer you further support based on your individual circumstance.
We know that having cervical cell changes or cervical cancer and needing treatment can be worrying, so we hope this information has helped you feel more prepared. Remember, your doctor or nurse is there to support you at every stage. We are also here to support you and our free Helpline is open if you want to talk through anything or simply have someone listen to your concerns on 0808 802 8000.
We also have a welcoming community in our online Forum, where you can get and give support. There are lots of conversations about cervical cell changes, cervical cancer and LLETZ, so you can choose to read existing threads or post your own messages.
If you have general questions about LLETZ, cervical cell changes or cervical cancer, our Ask the Expert service may be able to help. You can submit your question confidentially to our panel of experts and get a tailored reply. Jo’s Cervical Cancer Trust cannot give you medical advice or answers about any results. In this case, it is best to speak with your doctor.
