Increase in upper age of eligibility for breast cancer screening from 64 to 70
The upper age limit of eligibility for Breast Cancer Screening increased in England from 64 to 70 as a result of the NHS Cancer Plan, so women were offered an additional 2 rounds of screening.
Screening round length
The target round length (frequency) of breast cancer screening in England is every 3 years. However in practice there is variability in this due to local centre capacity. The exposures are round lengths of approximately 2 years and approximately 3 years
Screening test threshold
Radiologists and equivalent health professionals examine women's screening mammograms for potential signs of cancer, and recall some women for further diagnostic tests. Each has a different test threshold for recall, characterised by the proportion of previous cases that they have recalled.
