Exercise may alter gut bacteria in colon cancer survivors, small study hopes to find out

This study tests whether a moderate-to-vigorous exercise program can change the gut bacteria of people who have survived stage II or III colorectal cancer. Researchers will enroll 30 survivors and randomly assign them to either an exercise group or a health education group. The main goal is to see if the study is feasible, while also exploring how exercise affects gut bacteria and whether those changes relate to cancer outcomes and quality of life.
