[Medical] - Marathon Runners Face Unexpected Increase In Colon Cancer Risk

[UltimaOnline]

Over the course of about a year, Timothy Cannon, MD, who co-directs the Gastrointestinal Cancer Program at Inova Schar Cancer Institute, saw three strikingly similar patients. All of them were relatively young. All of them were not just healthy, but “extreme athletes” who ran long distances. And all of them had stage IV colon cancer.

“It was peculiar that these three all had running in common,” Cannon told Health—so he designed a study to learn more.

The results of that study, which were recently presented at an American Society of Clinical Oncology conference, suggest there may indeed be a link between distance running and severe disease. Out of 100 serious runners included in the study, 15 had a precursor of colon cancer—a finding that suggests “it’s a risk to run extreme distances and marathons,” Cannon said.

Cycling less damaging than running. The shock the legs and body/organs must endure when jogging is much worse.
