Screening is a way of identifying apparently healthy people who may have an increased risk of a particular condition. The NHS offers a range of free screening tests to different sections of the population.
There are a number of screening programmes that are rolled out nationally across the UK, including cervical, breast and bowel screening.
Cervical screening is offered to women aged 25 to 64 to check the health of cells in the cervix. It is offered every 3 years for those aged 26 to 49, and every 5 years from the ages of 50 to 64.
