NHS England has released its latest annual bowel cancer screening figures, covering the period from April 2024 to March 2025, and the results point to a persistent gap in participation among people in their 50s. The data show that the programme is identifying approximately 100 bowel cancers per week — a figure the health service is using to encourage those who have not yet returned their home testing kits to do so.
Participation Rates Among Those in Their 50s
According to NHS England's annual bowel screening figures, just 56.2% of 54-year-olds took part in the screening programme during the 2024–25 reporting year. That proportion — representing a little over half of those invited — is lower than participation seen in other age groups, a pattern that has prompted the health service to direct its latest appeal specifically at this demographic.
The home-based test, which is sent by post, requires a stool sample to be collected and returned for laboratory analysis. Despite the relative simplicity of the process, NHS England's data indicate that a substantial share of people in their 50s are not completing and returning their kits within the relevant period.
Scale of Detection Through Screening
The headline statistic from the newly published figures — around 100 cancers identified through the programme each week — underlines the volume of cases being caught via this route. Screening programmes are generally designed to detect disease at an earlier stage, when clinical options tend to be broader, though NHS England's published figures do not break down outcomes by stage of diagnosis in the data cited here.
The weekly detection figure applies across all age groups participating in the programme, and NHS England has highlighted it as evidence of the programme's reach and activity during the 2024–25 screening year.
The Push to Reach People in Their 50s
NHS England's campaign targets people in their 50s as a group where there is room to improve uptake. The figures suggest that, compared with older cohorts who have had longer exposure to bowel screening invitations, those earlier in the eligible age range are returning kits at a lower rate.
The health service has not, in the materials accompanying these figures, attributed the lower participation rate in this age group to any single factor. The data themselves, drawn from the NHS England annual bowel screening report, reflect completed kit returns logged during the April 2024 to March 2025 window.
Context for the Figures
Bowel cancer screening programmes that rely on home-based stool tests have been a feature of NHS cancer detection efforts for a number of years. The programme sends kits directly to eligible individuals, placing the initial step of participation in the hands of the recipient rather than requiring a clinical appointment.
The 56.2% participation rate among 54-year-olds reported by NHS England for 2024–25 means that nearly four in ten people in that age bracket did not return a kit during the reporting period. Whether unreturned kits reflect active decisions not to participate, kits that were not received, or kits that were received but not completed is not specified in the figures as published.
NHS England's publication of these figures alongside a targeted appeal to people in their 50s reflects an effort to use the detection data — approximately 100 cancers found per week across the programme — as a prompt for those who have not yet engaged with their invitation.
