Cervical screening

Published on 13 April 2022

Scottish Cervical Screening Programme

The cervical screening test (smear test) checks cells from the cervix – neck of the womb – for human papilloma virus (HPV), HPV causes 99% of all cervical cancers. If HPV is found, we'll then look at the same sample for cell changes. Monitoring or treating these cells is then possible. Without treatment, these changes can sometimes develop into cervical cancer. Cervical screening has proven to be effective in reducing the incidence and mortality (death) of cervical cancer.

Every year, cervical screening saves 5,000 lives in the UK. It also prevents eight out of 10 cervical cancers from developing.

Where does the cervical screening service take place?

We provide national coordination for the Scottish Cervical Screening Programme. Women get invites for their cervical screening in the post, with a supporting leaflet. Most women have the cervical screening test during an appointment at their GP surgery.

Who gets the cervical screening test and how does it work?

Cervical screening for eligible individuals is offered:

  • every five years for those between 25 and 64 years of age

Anyone on non-routine screening – where screening results have shown changes that require further investigation/follow-up – will get an invite up to 70 years of age. Eligible individuals include anyone with a cervix:

  • women
  • trans men and/or non-binary people

The test takes a small sample of cells from the cervix (neck of the womb). The cells are then sent to a laboratory, where they are checked for human papilloma virus (HPV). If HPV is found, the same cells will then be checked for any changes under a microscope. The pathway and subsequent follow-up will differ according to the test results.

Cervical intra-epithelial neoplasia (CIN) is the name for changes found in the cells of the cervix. Women in Scotland who’ve had treatment for CIN will be tested again for HPV as most changes in the cells of the cervix are caused by this virus. This normally takes place six months after treatment. Women who have a test that shows normal cervical cells and no HPV six months after treatment for CIN will be placed on non-routine three-yearly screening.

Further information for participants:

Find extra information on the importance of the test on NHS Inform. This includes details around:

  • what happens at the appointment
  • information on the link between cervical cancer and HPV
  • answers to some commonly asked questions

If you don't already have a GP, the NHS Inform website will also tell you how to register with a surgery.

The national cervical screening leaflet is available on the Health Scotland website. You can access this in an easy read version or in other languages.
