Bowel cancer screening

Overview

Bowel cancer is the fourth most common cancer in the UK, with around 46,600 new cases every year (2018-19, 2021). Patients who are diagnosed with bowel cancer at its earliest stage have more treatment options available that are more likely to be successful compared to patients diagnosed at a late stage.  

Bowel cancer screening reduces deaths from bowel cancer¹

. It aims to both prevent bowel cancer through the identification and removal of pre-cancerous polyps or adenomas ², and to detect it at an early stage before symptoms have a chance to develop. There are separate bowel cancer screening programmes for each UK nation, with differences between them. These are outlined in the table below and in our bowel cancer screening at a glance resource. (PDF, 160 KB) 

Bowel	England	Scotland	Wales	Northern Ireland
Age	50-74	50-74	50-74	60-74
Frequency	2 yearly On request from age 75	2 yearly On request from age 75	2 yearly	2 yearly
Test	Faecal Immunochemical Test (FIT)
Threshold	120 µg/g [a]	80 µg/g	80 µg/g	120 µg/g
Uptake [b]	68% (2023 - 24)	66% (2022 - 24)	66% (2023 - 24)	67% (2023 - 24)

^{[a] NHS England is beginning to reduce the FIT threshold to 80 µg/g across several early-adopter sites.}

^{[b] Caution should be taken when making comparisons across countries due to differences in time periods of data, changes to age ranges and/or differences in the definitions of coverage and uptake of screening.}
