This study is evaluating PreveCol, a new second-line stool test for people aged 50–69 who had a positive FIT/FOBT result and are already scheduled for a colonoscopy. It aims to find out if this test can help detect colorectal cancer earlier.
This trial tests a new blood test to screen for colorectal cancer in people at average risk. You would give a blood sample before your scheduled colonoscopy, and the results will be compared to the colonoscopy findings.
This study looks at how gut bacteria and immune activity differ in normal, pre-cancer, and cancer colon tissue. It may help researchers understand what changes in the body are linked to colon growth and how they could be targeted in the future.
This study looks at how diet and gut bacteria affect colon cancer risk in Black and Non-Hispanic White adults aged 45 to 75 who are at higher risk. You would donate mouth and stool samples and complete food recalls.
This study aims to find a better way to screen for stomach and colon cancers. You will be asked to provide a stool sample, and possibly have an endoscopy (a camera test), to see if combined screening can catch cancer early.
This study is looking at people who need an intestinal scope (endoscopy) for gut symptoms or bowel conditions like IBS, IBD, or possible colorectal cancer. Your results may help doctors better understand these long-term conditions and improve follow-up care.
