CERVICAL SMEAR TESTS
What is cervical screening?
Cervical screening is not a test for diagnosing cervical cancer. It
is a test to check the health of the cervix, which is the lower part
of the womb (often called the neck of the womb). For many women the
test results show that everything is fine. But for one in 10 women,
the test shows changes in the cells that can be caused by many things.
Most of these changes will not lead to cervical cancer
Why do I need cervical screening?
Cervical cancer can often be prevented. The signs that it may develop
can be spotted early on so it can be stopped before it even gets
started. Cervical screening saves over 1,000 lives in the UK each
year, but unfortunately about 1,500 women die from cervical cancer
in the UK every year
Should all women have the test?
We offer the test to all women aged between 25 and 64 but cervical
cancer is more common if you: first had sex at an early age; smoke;
do not use condoms; have had several sexual partners or have had
a sexual partner who has had several other partners; or take immunosuppressant
drugs (for example, after an organ transplant). If you have passed
the menopause, you still need to be tested to check that your cervix
is healthy. Ask your doctor for specific advice if you: have had
a hysterectomy; are over 65; have never had sex; or you are not sure
whether you still need to be tested
What is the NHS Cervical Screening Programme?
The programme makes sure that if you are aged between 25 and 64, you
will automatically receive an invitation. We will get your name from
your doctor's list. This means it is important that your doctor always
has your correct name and address. After your first cervical screen,
you will receive invitations every three to five years
Who will carry out my test?
A doctor or nurse will do your test. If you would prefer a female member
of staff, please ask when you make your appointment
Will I have to undress?
We will ask you to undress from the waist down, but if you wear a full
skirt you will not have to remove it
What happens during the test?
The doctor or nurse will ask you to lie down on a couch. They will
then gently put a small instrument, called a speculum, into your
vagina to hold it open. Then, they will wipe a smooth wooden or plastic
spatula over the cervix to pick up a few of the cells. They will
transfer these cells to a slide and send it away to be examined under
a microscope. The test takes just a few minutes
Does the test hurt?
You might experience some discomfort or pain - try to relax by taking
slow, deep breaths as it may hurt more if you are tense. If it is
painful, tell the doctor or nurse straight away as they may be able
to reduce your discomfort
Is there anything I should do before the test?
You cannot be tested during your period so make sure you get an appointment
before or after your period is due
Can I have sex before the test?
If you use a spermicide, a barrier method of contraception or a lubricant
jelly, you should not use these for 24 hours before the test as the
chemicals they contain may affect the test
When do I get my results?
When you have the test, the doctor or nurse will tell you how, where
and approximately when you will get your results. Make sure you have
received this information before you leave the surgery
How reliable is cervical screening?
Early detection and treatment can prevent 80 to 90% of cancers developing
but, like other screening tests, it is not perfect. It may not always
detect early cell changes that may lead to cancer. Abnormal cells
on your slide may not be recognised because: sometimes they do not
look much different from normal cells; there may be very few abnormal
cells on the slide; or the person reading your slide may miss the
abnormality (this happens occasionally, no matter how experienced
the reader is). About one in 10 tests have to be taken again because:
you may have an infection which needs treating before a clear slide
can be made; the cervical cells on your slide may have been hidden
by blood or mucus; there may not have been enough cervical cells
on your slide to give an accurate assessment; your sample may not
have been properly prepared; or your slide may have been broken.
If you have any unusual symptoms, such as bleeding after sex or between
periods, you should see your doctor
What does it mean if I am called back?
Only very rarely does it mean that you have cancer. It might simply
mean that your sample did not show up clearly and that we need to
take another test. This is called an 'unsatisfactory result'. On
the other hand, your result could identify some small changes in
the cells of the cervix. If abnormal changes (known as dyskariosis)
are detected, you will have what is called an 'abnormal result'.
This is not cancer. However, sometimes cancer will be found when
an abnormal test is investigated further. For more information about
what an abnormal result means, you can read the NHS cancer screening
programme leaflet 'What your abnormal result means'
Can anything be done about abnormal changes?
Yes. Your doctor or nurse will explain what needs to be done. They
may ask you to come back for more cervical screening tests because
the abnormal cells may return to normal by themselves. However, they
may ask you to go to hospital for a closer examination which is called
'colposcopy'. For more information about colposcopy, you can read
the NHS cancer screening programme leaflet 'The colposcopy examination'.
Treatment, if it is needed, is a minor procedure and is usually done
in an outpatient clinic which means you will not have to stay overnight
Can cervical screening prevent cancer?
Regular cervical screening every three to five years is the best way
to detect changes to the cervix early. Early detection and treatment
can prevent cancer developing in around 80 to 90% of cases
What happens to my sample once it has been
looked at?
The laboratory that looks at your sample will keep it for at least
10 years. They can then compare your latest result with the ones you
have had before. This is to make sure that you get any treatment you
may need. They may review all screening records, including your sample,
as part of our aim to offer a quality service and to help increase
the expertise of specialist staff. When a review shows that you should
have been cared for differently, we will contact you. We will offer
you information about the review of your case if you want to know it.

Summary
To help you decide whether or not to come for cervical screening, the
main benefits and difficulties of cervical screening are explained
below:
- Cervical screening reduces the risk of developing cervical cancer
- Due to cervical screening, cervical cancer is now an uncommon disease in this country
- Cervical cancer rates have halved since the 1980s, largely due to most women regularly having cervical screening
- Cervical screening by the NHS saves over 1000 lives each year
- In one in 10 tests, the cells cannot be seen properly under the microscope and the test must be taken again
- The test can show minor abnormalities in cervical cells which would have cleared up on their own and women would never have known about them if they had not been for screening. It is not yet clear which minor abnormalities would develop into cancer and which would not. Many women worry when a minor abnormality is found
- Cervical screening does not pick up every abnormality of the cervix
- Regular cervical screening can prevent about 80 to 90% of cervical cancers developing, but it does not prevent every case
- Some women find having the test an unpleasant experience
