This article was originally published in 2017 during Cervical Screening Awareness Week. It has now been reviewed and updated.
Cervical screening, also known as the smear test, isn’t actually a test for cancer.
Although it does sometimes find cervical cancers, cervical screening instead aims to prevent cancer developing in the first place.
It tests for a virus called human papillomavirus (HPV). Some types of HPV (called ‘high risk’) can cause cervical cells to become abnormal, which can lead to cancer. If high risk HPV is found, the cells are examined to look for changes which could become cancerous in the future.
Most people in the UK who receive an invitation for cervical screening take part. But the test can seem a bit daunting, particularly if you’ve never had it before.
While it does have some possible risks, the test prevents at least 2,000 cervical cancer deaths each year in the UK.
It’s completely up to the individual whether to go or not. But the answers to these 6 questions could help you decide.
1. Who’s it for?
Cervical screening is for everyone with a cervix, regardless of sexual or gender identity. This includes women, some transgender men and some non-binary people. In the UK it’s offered to those aged 25 to 64. And you’ll need to be registered as female with a doctor to be invited.
If you’re not registered as female and have a cervix, you can ask your GP or practice nurse to arrange screening for you. There are also clinics specialising in healthcare for trans and non-binary people which offer screening.
Our website has more information on screening for trans and non-binary people.
Screening isn’t offered to people under 25 because research shows that, for this age group, it would actually do more harm than good. If you are over 65 and have never had cervical screening, you can ask your GP for a test if you want one.
Most people will have HPV at some point in their lives, it’s completely normal. The majority of those who have HPV won’t have any problems, but HPV is the cause of most cases of cervical cancer. You should consider screening even if you’ve had the HPV vaccine, which protects against the types of HPV that cause most, but not all, cervical cancers.
Like other screening programmes, cervical screening is for people who don’t have any symptoms. So if you’re worried about a change to your body that is unusual for you or doesn’t go away, whether you’re of screening age or not, you should speak to your doctor. Even if you’ve had screening recently or are due to go soon, don’t ignore it.
2. What happens?
It’s usually done by a practice nurse at a doctor’s surgery. After a chat to talk through the test and answer any questions, the nurse will ask the patient to lie on their back with their knees raised and parted. They then use a speculum, which opens the vagina, to be able to see the cervix.
A small, soft brush is used to collect some cells from the cervix. The doctor or nurse will then remove the speculum and let the patient know that the test is done.
The cells that have been collected are sent off to a lab. They’ll be tested for high risk HPV and, if it’s found, they will also be checked for any abnormal changes.
3. What if I’m embarrassed?
It’s normal to feel self-conscious, especially on the first visit.
“When women are invited for routine cervical screening, they may feel a little anxious about exposing an intimate part of their bodies,” says Mary Hoey, one of our senior cancer information nurses.
“It can be reassuring for women to know that most of these tests are done by practice nurses, who are very experienced explaining about and doing cervical screening tests. This can be very important in helping to make women feel comfortable and relaxed.”
When booking the appointment, you can ask for a man or woman to do the test. You can also ask to take someone with you to the appointment (this can be a friend or family member, or someone who works at the practice).
4. Does it hurt?
Most people won’t experience pain from cervical screening, but sometimes the speculum can be uncomfortable.
In some cases, the muscles around the vagina can tighten, which can make it difficult to insert the speculum, and sometimes this is painful. This is known as vaginismus – people with this condition often find it painful to have penetrative sex, or to use tampons.
Speak with your doctor or nurse if you have concerns about this. And you can always ask the nurse to stop at any point if you feel pain or too much discomfort.
5. Does it take long?
Most cervical screening appointments are quicker than a normal doctor’s appointment, and you’ll be able to carry on with your day afterwards.
Some practices offer cervical screening at weekends or outside normal working hours too.
After the test, the nurse will let you know when to expect your results, which will be posted to your home address.
6. What happens if I get an abnormal result?
The vast majority of cervical screening results are normal.
If the test finds high-risk HPV but no abnormal cells, you will be invited back early for screening in a year’s time.
If the test finds high-risk HPV and abnormal changes in the cells, you will be invited to go for a different type of test called a colposcopy. A colposcopy helps to show how different the changed cells are from the norm, so that doctors can suggest the best options for managing them.
Finding abnormal cells doesn’t mean you have cancer. In fact, finding these cells and treating them can actually prevent cervical cancer from developing.
It’s rare to find cervical cancer through screening, and as more people are screened, cervical cancer is becoming even less common.

Noted previous comments from ladies my age (71) Still think it should be available if you want to request it. Every life is important.

Thank you for your comment.
Cervical cancer usually develops very slowly, and the benefits of cervical screening can last for years after you’ve been tested. This means that it is unlikely that a person over the age of 64 who has been regularly screened will go on to develop the disease.
But if you are 65 or over and have never had cervical screening, you can ask your GP for a cervical screening appointment if you want one.
Cervical screening works very well but, like any screening test, it isn’t perfect. Screening has harms as well as benefits, so it’s offered at ages when the benefits are biggest and the harms are smallest.
In people who are aged 65 and over, the balance of harms and benefits is less clear, and the risks of screening may be greater. You can read more about cervical screening and its possible benefits and harms on our website.
Cervical screening is still going ahead in the UK. But because of COVID-19, there are delays. You might have to wait longer for your screening test or a follow-up appointment.
Screening is for people without symptoms. No matter your age, if you notice any changes to your body that are unusual for you or don’t go away, tell your doctor. Even if you have been screened recently or are waiting to be screened – if something’s not normal for you, get it checked out.

I had a smear test 18/11/2021. It is important to have these tests. I went for a walk then to the gym afterwards. Women have different ideas about having a smear. For me, relaxing made it much easier. Having a smear test could be life changing.

I’m so happy to have had the HPV vaccine as a teenager and am greatful to be taking my smear test soon

How do I go about having a screening at 71 years old and is it necessary? I had my ovaries removed several years ago and have two adult sons.
Valerie k Evans August 3, 2017
I was 70 in June would I be able to have a test

Hi Valerie and Bonnie,
Thanks for your comments. In the UK, cervical screening is offered to people aged 25 – 64. People aged 65 or over are only invited if their previous cervical screening showed abnormal cell changes, or if they haven’t been screened since age 50. Cervical screening is for people without symptoms, and doesn’t check for other cancer types like ovarian cancer. But whether you’re eligible for screening or not, if you notice any changes to your body that are unusual for you or don’t go away, tell your doctor.

I think this is great as it’s free & should be taken up… I was slightly nervous the first time but now I go regularly & find the surgery nurses are always putting me at my ease …….
