Colorectal cancer is a preventable and/or a treatable cancer, but at least 43% of the United States population is not up-to-date with screening. Although 90% of colorectal cancer screening is done using colonoscopy, most other countries use fecal immunochemical tests, reserving colonoscopy for those with a positive fecal immunochemical test. This project will provide the foundation for a paradigm shift for colorectal cancer screening in the United States by identifying how well 5 different FITs work for detecting screening relevant neoplasia, thus reducing morbidity and mortality for colorectal cancer.
