💬In plain words
What the trial is, and whether it could suit you
This clinical trial evaluates the effects of exercise therapy on signs of colorectal cancer in colon tissue and blood in people who completed pelvic radiation therapy for prostate cancer. People who get radiation in the pelvic area have a higher chance of developing colon cancer years later. This is because radiation can cause new mutations and inflammation. Research shows that exercise lowers colon cancer risk by about 30%. The results of this trial may help researchers better understand how exercise affects the development of colorectal cancer in patients who were treated with pelvic radiation therapy for prostate cancer.
