High-risk individuals are those with a cluster of 3x (or more) FDRs diagnosed with bowel cancer at any age across more than one generation (the person referred to us will need to be a FDR of at least one affected individual). If an individual is assessed as having a high familial risk of bowel cancer, they should be offered colonoscopic surveillance every 5 years from the age of 40*.
*If a high risk family meets the Amsterdam Criteria (add in link), they may be offered more frequent surveillance or additional genetic assessment by their specialist service.
Please see the British Society of Gastroenterology Guidelines (2019) for more information (add in link).
