COLO-COHORT aims to develop a “risk stratification tool” to help determine which patients are at highest risk of having polyps or cancer; this tool will be able to be used in the future to work out which patients need to be referred to endoscopy for investigation.

This study seeks to understand why some people may not complete a poo test, that looks for traces of blood, after going to the GP with symptoms of possible bowel cancer. By understanding what problems people experience, and whether there are particular groups of patients who experience these, we can work to develop strategies to support people to complete this test.
