People in their 50s are returning bowel cancer screening kits at lower rates than other age groups, according to the latest annual figures published by NHS England. The data, which covers the period from April 2024 to March 2025, has prompted the health service to call on this demographic to complete their tests.
What the Figures Show
Among the specific age points examined, just 56.2% of 54-year-olds took part in bowel cancer screening during the reporting year, according to NHS England's annual bowel screening figures. That proportion places this age group behind older cohorts in terms of participation, a gap that NHS England has flagged as a concern given what screening is already finding.
Despite the lower uptake, the programme is still detecting approximately 100 bowel cancers every week among people in their 50s. NHS England has highlighted that figure as an indication of the potential impact that broader participation could have across this demographic.
Why Uptake Matters
Bowel cancer screening is designed to identify abnormalities before symptoms develop, at a stage when intervention is generally more straightforward. When cases are found through screening rather than after a person notices symptoms, the cancer is more likely to be at an earlier stage.
The gap in participation among people in their 50s means that a substantial portion of this group is not benefiting from that early-detection opportunity. NHS England's annual data makes clear that the 100-cancers-per-week detection rate is being achieved with only around half of eligible 54-year-olds participating — a figure that implies a considerable number of cases may be going undetected in those who do not return their kits.
How the Screening Process Works
The NHS bowel cancer screening programme sends eligible individuals a home testing kit. The test analyses a stool sample for traces of blood, which can be an early indicator of bowel abnormalities including cancer. Participants complete the test at home and return the kit by post for laboratory analysis. Those whose results indicate a need for further investigation are referred for a colonoscopy.
The at-home format is intended to make participation as straightforward as possible, which makes the lower uptake among people in their 50s a particular focus for NHS England's current messaging.
The Broader Picture
The annual bowel screening figures released by NHS England provide a system-wide view of how the programme is performing across age groups. The 2024–25 data shows that while the programme is functioning as an effective detection tool — evidenced by the weekly cancer-find rate — participation levels among those in their 50s remain an area where improvement is sought.
NHS England has not specified in the published figures what proportion of the cancers detected at the 100-per-week rate are found at early versus later stages, though the general principle of screening programmes is that earlier detection is associated with better outcomes.
The health service's public communication around these figures is focused on encouraging non-participants in the 50s age bracket to complete and return their kits when they arrive, framing the current detection rate as evidence that the screening process is working for those who do engage with it.
