Your guide to NHS cervical screening

You can choose if you take part in cervical screening. This leaflet aims
to help you decide. Cervical screening used to be called a ‘smear test’.
Why the NHS offers cervical screening
We offer cervical screening to check the health of your cervix
and help prevent cervical cancer. We look for high-risk human
papillomavirus (HPV). This is because it can cause abnormal changes
that may lead to cervical cancer.
Finding and treating any changes early can prevent most cases of
cervical cancer. Cervical cancer mostly affects women and people
who have a cervix under the age of 45, but abnormal changes can
happen at any age.
Cervical screening saves thousands of lives each year in the UK.
Regular cervical screening is important. You’re still at risk of cervical
cancer even if you:

  • have had the HPV vaccine
  • have only had 1 sexual partner
  • haven’t had penetrative sex
  • have had the same partner, or have not had sex, for a long time
  • are a lesbian or bisexual
  • are a trans man or a non-binary person with a cervix
  • have had a subtotal (partial) hysterectomy that did not remove
    your cervix.
    If you’ve had a total hysterectomy, you do not have a womb or cervix.
    This means you do not need cervical screening.
    Who we invite for cervical screening
    We routinely invite women aged 25 to 64 every 5 years. Most cervical
    cancers develop between these ages.
    Your GP surgery gives us your contact information. Please make sure
    they have the correct details, including your:
  • name
  • date of birth
  • address
  • mobile number
  • email address.
    Your invitation will give you information about booking cervical
    screening. You can book as soon as you’re invited.
    Trans men and non-binary people with a cervix are also eligible
    for cervical screening. How you’re invited will depend on how your
    gender is recorded in your GP patient record:
  • If you’re listed as female, you’ll receive invitations automatically.
  • If not, you can ‘opt in’ to receive routine invitations. You can do
    this by contacting a cervical screening provider, such as your GP, a
    sexual health clinic or a transgender health clinic.
    If you’re unsure, contact your GP. For more information, go to
    www.gov.uk/trans-non-binary-screening.

    Cervical cancer is a cancer found anywhere in the cervix.
    The cervix is the opening to your womb from your vagina. It’s part
    of the reproductive system and is sometimes called the neck of the
    womb.
    Nearly all cervical cancers are caused by an infection with certain
    high-risk types of human papillomavirus (HPV).
    HPV is the name for a very common group of viruses. Most HPV
    viruses are low-risk and do not cause any problems.
    HPV viruses spread easily. You can get HPV from any kind of sexual
    contact, including:
  • any skin-to-skin contact of the genital area
  • vaginal, anal or oral sex
  • sharing sex toys.
    You can catch HPV even if you have not had penetrative sex. Most
    people get some type of HPV during their lives. It’s nothing to feel
    ashamed or embarrassed about.
    You can have HPV for many years even if you have not been sexually
    active or had a new partner. HPV does not always cause symptoms, so
    you may not know if you have it.
    Your body will usually get rid of HPV, but if high-risk HPV stays in your
    body, it can cause changes to the cells in your cervix. These changes
    may become cervical cancer if untreated.
    If you do not have a high-risk type of HPV, it’s very unlikely you’ll get
    cervical cancer. This includes if you’ve had abnormal cell changes in
    your cervix before.

    Cervical screening is usually done by a female nurse or doctor. You
    can ask for this when you make your appointment, and your GP
    surgery or sexual health clinic will make sure a female healthcare
    professional is available.
    They’ll take a sample of cells from your cervix with a soft brush for
    testing at a lab. After this, most people will not need any further tests.
    If we find high-risk HPV in your sample, we also check for any
    abnormal changes in the cells. This helps to make cervical screening
    results more accurate.
    If we find changes, you may need a different test called a colposcopy
    to look at your cervix more closely. We’ll offer you an appointment to
    discuss this if you need it.
    At your appointment
    The nurse or doctor will explain to you what to expect at each step of
    your screening:
  1. You will have privacy to get undressed from the waist down. You
    may want to wear something you can leave on, like a long jumper,
    dress or skirt.
  2. You will be given a paper sheet or towel to put over your waist
    area during your screening.
  3. You’ll usually lie back with your legs bent, feet together and knees
    apart. You can ask to be in a different position, such as on your
    side. Sometimes, you may need to change position during the
    test.
  4. The nurse or doctor will gently put a smooth, tube-shaped tool
    called a speculum into your vagina. They may use a small amount
    of lubricant to help reduce any discomfort. You can ask for a
    smaller speculum. You can also ask to insert the speculum yourself
    at first.
  5. They’ll open the speculum to see your cervix. Using a soft brush,
    they’ll take a small sample of cells from your cervix. You may feel
    some discomfort. You can try breathing exercises to help you
    relax.
  6. They’ll close and remove the speculum and leave you to get
    dressed. They can give you tissues to wipe away any lubricant.
    The cervical screening test itself should take less than 5 minutes. The
    whole appointment should take about 10 minutes.
    The nurse or doctor will be trained to support you. You can also
    bring someone with you, such as a friend, relative, partner or support
    worker. They can be in the room with you during your appointment.
    If you need to empty your bladder before your screening, let the
    nurse or doctor know. You can ask for adjustments to help you feel
    more comfortable and you should say if you feel any pain.
    Go to www.nhs.uk/cervical-screening-appointment to watch a video
    of a cervical screening. It shows an illustrated view of inside the body,
    and explains what happens during the test.

    You may need support to attend your cervical screening. When you
    book, tell your GP surgery or sexual health clinic if you need any
    reasonable adjustments, such as:
  • a longer or double appointment
  • information in other languages or formats or an interpreter
  • a chaperone in the room with you (another trained member of
    staff)
  • an appointment with a trusted doctor or nurse who you already
    have a good relationship with.
    You should:
  • book your screening for when you’re not having a period – this
    includes the 2 days before or after you bleed
  • wait until after any treatment for unusual vaginal discharge or a
    pelvic infection
  • let them know if you are or could be pregnant, as you may need
    to delay your screening.
    Most people should avoid vaginal medicines, lubricants and creams
    for 2 days before cervical screening. However, if you think your
    appointment may be more difficult because of vaginal dryness, they
    may prescribe a vaginal oestrogen cream or pessary before your
    screening.
    Some people feel understandably anxious about cervical screening.
    This may be because of a mental health condition, past traumatic
    experiences, sexual abuse or domestic violence. You are in control of
    your cervical screening and can ask to stop at any time. You can read
    our guidance for people who find it difficult to attend at
    www.gov.uk/cervical-screening-support.
    Cervical screening results
    The nurse or doctor will tell you when you can expect your results.
    There are 3 possible results:
  • HPV negative
  • HPV positive, no abnormal cells
  • HPV positive and abnormal cells.
    Sometimes we cannot get a result from your sample. If this happens,
    we’ll invite you for another cervical screening in 3 months. It does not
    mean anything is wrong.
    HPV negative Most people (around 87 in 100) have this result. It means we did not find high-risk HPV in your sample. Your risk of getting cervical cancer is very low. We do not need to check your sample for abnormal cell changes in your cervix. We’ll usually invite you for screening again in 5 years. Some people may be invited sooner depending on previous test results. Your results letter will confirm this.
    10 Your guide to NHS cervical screening
  • 11 HPV positive, no abnormal cells.Around 9 in 100 people have this result.
    It means we found high-risk HPV in your sample, but there were no abnormal cell changes. We’ll invite you for screening again in 1 year. We ask you to come
    sooner than usual so we can check if your body has got rid of the high-risk HPV, which happens in most cases. If you still have high-risk HPV but no abnormal cell changes, we’ll
    invite you for screening again 1 year later. If you still have high-risk. HPV after 2 years, we’ll invite you for a colposcopy to look at your cervix more closely.
    HPV positive and abnormal cells. Around 4 in 100 people have this result. It means we found high-risk HPV in your sample and abnormal changes to the cells of your cervix. Your results letter will explain this in more detail.
    We’ll refer you for a colposcopy. It’s like cervical screening, but it’s done in hospital. A specialist nurse or doctor will look at your cervix using a magnifying lens. This is called a colposcope and it stays outside of the body. If needed, they may take a small tissue sample called a biopsy. You can read more at www.nhs.uk/colposcopy.
    Most people who have a colposcopy do not have cervical cancer.
    Results for every 100 people who have cervical screening
    The NHS records your result on a national database. This means we can
    compare your regular screening results. We will keep your sample for 10
    years.
    87 do not need further tests (HPV negative)
    9 are invited for screening again in 1 year (HPV positive, no abnormal cells)
    4 are referred for a colposcopy (HPV positive and abnormal cells)
  • Cervical cancer symptoms
  • Symptoms of cervical cancer may include:
  • vaginal bleeding that’s unusual for you
  • bleeding during or after sex, between your periods or after the
    menopause (when your periods have stopped for 12 months or
    more)
  • having heavier periods than usual
  • changes to your vaginal discharge
  • pain during sex
  • pain in your lower back, between your hip bones (pelvis), or in
    your lower tummy.
    These symptoms are very common and can have many causes, but it’s
    important to get them checked by a GP. If cancer is the cause, finding
    it early means treatment is more likely to be effective.
    If you have another condition, like fibroids or endometriosis, see a GP
    if your symptoms change, get worse or do not feel normal for you.
    Who is more likely to get cervical cancer
    Cervical cancer mostly affects women and people with a cervix under
    the age of 45, but it can happen at any age.
    You may be more likely to get cervical cancer if:
  • you’re under 45 – cervical cancer is more common in younger
    people
  • you have a weakened immune system, for example if you have
    HIV or AIDS
  • you have given birth to many children or had children at an early
    age (under 17 years old)
  • your mother took the hormonal medicine diethylstilbestrol while
    pregnant with you
  • you’ve had vaginal, vulval, kidney or bladder cancer in the past
  • you smoke
  • you’ve taken the contraceptive pill for more than 5 years – this
    only slightly increases your risk.
    Possible risks of cervical screening
    No screening test is 100% reliable.
    In cervical screening, this is because:
  • an HPV infection or abnormal cells can sometimes be missed (a
    ‘false negative’ result)
  • there is a small chance that a result says abnormal cells are found
    when the cervix is normal (a ‘false positive’ result)
  • there is a small risk of abnormal cells developing and turning into
    cancer in between screening tests.
    Cervical screening is not a check for other cancers of the reproductive
    system, such as ovary, womb, vulval or vaginal cancer. Do not wait to
    contact a GP if you have any concerns.
    Possible risks of having a colposcopy
    Most people will not need a referral for a colposcopy and will not
    need to have abnormal cells removed. If you do need cells removed,
    there’s a small risk of bleeding and infection. You’ll get more
    information to help you decide if you need a colposcopy.
    Cervical cancer symptoms
    Symptoms of cervical cancer may include:

  • You can lower your chance of getting cervical cancer by using
    condoms, stopping smoking and eating a balanced diet.
    You cannot get cervical cancer if you’ve had surgery to remove your
    womb and cervix.
    Cervical cancer and the HPV vaccine
    The HPV vaccine helps protect against the HPV virus, which causes
    most cervical cancers.
    It’s recommended for children aged 12 to 13 years old and people
    at higher risk from HPV. If you were eligible but missed getting
    vaccinated when you were 12 or 13, contact your GP surgery. You can
    read more at www.nhs.uk/hpv-vaccine.
    It’s still important to attend cervical screening appointments, even
    if you’ve been vaccinated against HPV. It does not protect you from
    all types of HPV, so there’s still a small chance you could get cervical
    cancer.
    Cervical screening and HPV vaccination give the best protection from
    cervical cancer.
    Clinical trials
    You may be asked if you want to take part in a clinical trial. These
    are medical research studies. Any trial you are offered will gather
    information about the best types of screening tests or treatments so
    we can improve services in the future. You can choose whether to
    take part or not.
