The main questions it aims to answer are: 1. Is the Gixam Device effective in identifying persons with pre-cancer or cancer in the colon and rectum that have received a negative FIT result? 2. Is the use of the Gixam device safe? Gixam test result will be compared to the findings of a standard of care screening colonoscopy. Study participants will: 1. Undergo the Gixam test 2. Take a FIT at home and ship to a laboratory. 3. Undergo a standard of care screening colonoscopy.
