Read our Colorectal Cancer research guide →Bowel cancer is a leading cause of cancer death in the UK, but current screening only catches about 1 in 10 cancers. This study is collecting health information, measurements, and optional samples (blood, stool, or saliva) from up to 15,000 people to build a prediction model that could help doctors identify who is at highest risk for bowel cancer before symptoms appear.
Right now, bowel cancer screening only considers age, but we know many other factors—like smoking, weight, family history, and even gut bacteria—affect your risk. This study aims to create a better way to identify high-risk patients so screening can be more targeted and more lives can be saved.
If you join, you'll complete a health questionnaire about your medical history, smoking, alcohol use, and family history. You'll have your height, weight, and waist measured. Depending on why you're having your colonoscopy, you may provide blood, stool, or saliva samples for testing. You'll also answer a food questionnaire or brief survey about your experience. The whole process happens around your scheduled colonoscopy visit. Alternatively, some participants may simply consent to be contacted for future bowel cancer research studies.
