Updated 4 April 2018: A data quality issue has been identified which relates to first invitation uptake data for a subset of Breast Screening Units in 2016-17. Additional footnotes have been added to the Main Report, Data Tables, Appendices document and the Interactive Dashboard. Women between the ages of 50 and 70 are invited for regular breast screening (every three years) under a national programme. Screening is intended to reduce mortality by detecting breast cancer at an early stage when there is a better chance of successful treatment. This report presents information about the NHS Breast Screening Programme in England in 2016-17 and includes data on women invited for breast screening, coverage, uptake of invitations, outcomes of screening and cancers detected. The publication also features an online interactive dashboard to complement the existing publication resources. The dashboard can be accessed by clicking on the icon above or by clicking on the link in the resources section below. This tool is in Microsoft PowerBI which does not fully support all accessibility needs. If you need further assistance, please contact us for help.
