Should I use this page, or skip it?
Use this page if you have a cervix and need who is invited in England, what the HPV test means, and when bleeding still needs a GP. Skip it and call 999 if you collapse, bleed heavily and feel faint, or cannot breathe. See a GP now for bleeding between periods, after sex, or after menopause.
This is a screening explainer, not a diagnosis. It will not interpret a personal result letter. It will help you decide whether to book, what HPV-positive means, and when symptoms sit outside the programme.
If you already have a cancer diagnosis, go to cervical cancer. If you want the virus explained, see human papillomavirus (HPV). If the problem is bleeding rather than an invitation, start with vaginal bleeding.
What is cervical screening — and is it a test for cancer?
Cervical screening, still often called a smear test, checks the health of the cervix to help prevent cervical cancer. In England the sample is tested for high-risk HPV first. It is not a test that diagnoses cancer. Most people who attend do not have cancer. Finding HPV or cell changes means monitoring or treatment can happen before cancer develops.
The old smear looked at cells under a microscope first. HPV primary screening looks for high-risk HPV, the virus linked to almost all cervical cancers. If HPV is not found, the cells are not usually checked further. If HPV is found, the same sample can be looked at for cell changes.
The NHS and Cancer Research UK both treat this as a prevention test, not a cancer diagnosis. A normal result is common. An abnormal result usually means watch or treat cell changes. Screening samples a moment in time, which is why symptoms between invites still need a GP.
Who is invited in England, and how often?
In England, women and people with a cervix aged 25 to 64 are invited. The usual pattern is every 3 years from 25 to 49 and every 5 years from 50 to 64. Follow the date on your invitation letter. If HPV is found you will be invited sooner.
You usually get a first invite a few months before you turn 25, by NHS App, text or letter. If you are registered as female with a GP, invites are automatic. If you have a cervix and are registered as male, ask the surgery or a sexual health clinic to include you. Scotland, Wales and Northern Ireland set their own intervals — follow the letter you were sent.
| Situation | What usually happens in England | What you should do |
|---|---|---|
| Age 25 to 49, routine screen | Invited every 3 years | Book when the invite arrives; follow the next date on your letter |
| Age 50 to 64, routine screen | Invited every 5 years | Book when invited; do not wait for symptoms |
| HPV found | Earlier recall, or colposcopy if cell changes are present | Attend the follow-up you are offered |
| Age 65 or older | Routine invites usually stop if recent tests were normal | Ask a GP if you have never been screened, or not since 50 |
| Total hysterectomy (cervix removed) | Screening usually stops | Confirm with your care team; ignore stray invites only after they have checked |
Your letter is the source of truth because HPV results change the interval. Some people whose latest test was HPV-negative are now recalled at 5 years even under 50. Do not invent a date. Read the one you were sent.
What happens at the appointment?
You lie on a couch. A nurse or doctor inserts a speculum so they can see the cervix, then uses a small soft brush to take a sample. It usually takes a few minutes. Most people feel brief discomfort, not severe pain. Tell the nurse if it hurts — they can often use a smaller speculum or pause.
You can ask for a chaperone, a female clinician if available, or to insert the speculum yourself. Say if tests are painful or difficult. Light spotting afterwards can happen. Heavy bleeding, feeling faint, or severe pain is not the usual pattern — contact the surgery or NHS 111.
Do not use the appointment as a substitute for reporting vaginal bleeding. Mention bleeding, pain or discharge at the start.
What do HPV results mean?
Results usually come via the NHS App or a letter. HPV not found means your risk of cervical cancer is very low and you return to routine screening. An unclear sample means the test is repeated. HPV found with no cell changes means earlier recall. HPV found with cell changes usually means a colposcopy.
The nurse should tell you when to expect results. If that window passes, call the GP surgery — a delay does not mean something is wrong.
| Result | What it means | Typical next step |
|---|---|---|
| HPV not found (HPV negative) | Very low risk of cervical cancer from this sample | Routine screening at your usual interval |
| Unclear or inadequate | The lab could not use the sample | Repeat the test, often after a short wait |
| HPV found, no cell changes | HPV is present; cells look normal | Earlier screening, often in a year |
| HPV found, cell changes | Cells need a closer look | Colposcopy in hospital |
A colposcopy is a closer look at the cervix in hospital. NHS advice is that cell changes will not suddenly become cancer while you wait; still attend. Treatment, if needed, removes or destroys changed cells so they cannot become cancer later. HPV on a result is common and is not a judgement on anyone’s sex life. See HPV.
Does the HPV vaccine replace screening?
No. The NHS HPV vaccine reduces the chance of the HPV types that cause most cervical cancers, but it does not cover every type. You still need cervical screening from 25 even if you were vaccinated at school. Screening and vaccination work together. Do not skip screening because you were vaccinated.
In England the vaccine is offered to children aged 12 to 13, with catch-up for some younger adults who missed it. The vaccine lowers the chance of the highest-risk types; screening still finds HPV or cell changes that occur. Parents looking for school vaccine dates should use the NHS HPV vaccine page, not this guide.
What if I bleed between screens, or I am overdue?
Screening is not a substitute for checking new symptoms. See a GP if you have bleeding between periods, after sex, or after the menopause, or unusual vaginal discharge. Do not wait for the next invitation. If you missed a screen, you can still book — you do not have to wait for another letter.
Those patterns can be how cervical cancer shows itself, though far more often the cause is something else, including postmenopausal bleeding. Symptoms go to a GP; invitations go to a screening clinic. If you are overdue, book — sexual health clinics can sometimes offer screening. A recent normal smear does not explain bleeding today.
Who is this page not for?
This page is not a diagnosis of cervical cancer and it cannot interpret your personal result letter. It is not for someone who is bleeding heavily and unwell now — that needs urgent care. It is not a booking service. Parents looking for the school HPV vaccine should use the NHS HPV vaccine page, not this screening guide.
It is the wrong page if you do not have a cervix. If an invite arrives anyway, ask the surgery to stop them. If you need a service rather than an explanation, use the pharmacy, GP, 111 or A&E guide.
Common questions about the cervical screening
- Does cervical screening hurt?
- Most people feel brief discomfort when the speculum goes in and the sample is taken. It is usually over in a few minutes. Tell the nurse if it is painful. They can often use a smaller speculum, more lubricant, or pause. Light spotting afterwards can happen and usually settles.
- What happens if HPV is found?
- HPV found with no cell changes usually means you are invited back sooner, often in a year. HPV found with abnormal cell changes usually means a colposcopy, a closer look at the cervix in hospital. HPV on a screening test does not mean you have cancer, and it does not mean a partner has been unfaithful.
- Do I still need screening after the HPV vaccine?
- Yes. The NHS HPV vaccine protects against the types that cause most cervical cancers, but not every type. You still need screening from 25 even if you were vaccinated at school. Vaccination and screening work together. Skipping screens because you had the vaccine leaves a gap.
- Do I need screening after a hysterectomy?
- It depends whether your cervix was removed. After a total hysterectomy you usually leave the programme. After a sub-total hysterectomy the cervix remains, so screening still matters. Your care team should tell you. If invitations keep arriving and you are unsure, ask the GP surgery to check.
- Why is screening not offered under 25 in England?
- NHS guidance is that cervical cancer is very rare under 25, while cell changes that often go back to normal are common. Screening younger people can lead to treatment they do not need. Under 25, new symptoms such as bleeding between periods or after sex still need a GP, not a wait until your first invite.
- What if I missed my last invitation?
- You do not have to wait for another letter. Contact your GP surgery or a sexual health clinic that offers screening and book. If you are 65 or older and have never been screened, or not since 50, you can ask a GP about a test. Follow the interval on the letter you are given next.
- Should I delay screening if I am pregnant?
- Routine screening is often postponed until after the baby is born, but that is an individual decision. Ask your midwife or GP rather than cancelling without advice, especially if you are overdue or a previous result needed follow-up. New bleeding in pregnancy is a separate problem and needs clinical advice, not a smear as the first step.
