Disadvantages of Cervical screening test
As with all screening tests, cervical screening is not 100% accurate. Regular screening can stop up to 75 per cent of cancers developing, but it doesn’t prevent every case.
Cervical screening detects abnormalities early on, giving a better chance of successful treatment before the cells can develop into cancer.
It’s not yet known which early changes in cervical cells will develop into cancer, and which will not. This means some women will be treated for abnormalities that may have cleared up on their own.
Cervical screening saves up to 1000 lives a year in England and Wales.
