New Research Shows Exercise Significantly Improves Survival in Colon Cancer Patients

Groundbreaking new evidence underscores the role of exercise in enhancing survival rates among cancer patients.

In a randomized controlled trial involving nearly 900 participants across 55 cancer centers in six countries, those who engaged in a structured exercise program demonstrated longer periods without cancer recurrence or new cancers. Compared to the control group, the exercise participants experienced a 37% reduction in mortality risk and a 28% decrease in the risk of cancer returning or developing anew.

While previous observational studies hinted at such benefits, they did not establish a definitive cause-and-effect relationship.

“This study provides conclusive proof that exercise extends beyond improving quality of life and fitness—it actively increases survival and should become a standard part of cancer care,” stated Dr. Christopher Booth, senior author of the study and oncology professor at Queen’s University in Canada.

Published recently in a leading medical journal, the trial focused on patients with Stage III or high-risk Stage II colon cancer who underwent standard surgery and chemotherapy. Participants were randomly assigned either to a control group receiving educational resources on physical activity and nutrition, or to an intervention group that, in addition, received ongoing guidance from a 'physical activity consultant'—a role combining elements of personal training and coaching—over three years to boost and maintain aerobic exercise routines. Patients selected from various activities including biking, jogging, swimming, and kayaking, with most favoring brisk walks lasting 45 minutes, four times weekly.

After five years, 80% of those in the exercise group remained free of disease, compared to 74% in the control group. Over an eight-year span, the exercise program prevented one death for every 14 participants who followed the regimen.
