Revolutionary Findings from Queen's Study

A groundbreaking study from Queen’s University has upended traditional cancer care by proving that regular exercise significantly lowers the risk of colon cancer recurrence. After 15 years in the making, this research could change the lives of countless survivors.

In-Depth Research and Methodology

Conducted by a team from the Canadian Cancer Trials Group and Kingston Health Sciences Centre, this extensive trial followed 889 patients across 55 clinical centers for over 15 years. The research, published in the prestigious New England Journal of Medicine in June 2025, categorized survivors who had undergone surgery and chemotherapy into two distinct groups:

1. **Control Group**: Received health education materials only.

2. **Exercise Group**: Besides the health materials, this group participated in a structured exercise program led by a certified physical activity consultant. The aim was to boost their recreational exercise to at least 10 metabolic activity equivalent task (MET) hours each week for the first six months, and to sustain or increase that level for the next two and a half years.

Results That Shine Bright!

The results were nothing short of impressive. Patients engaging in the structured exercise program were found to be 28% less likely to experience a recurrence of cancer, develop new cancers, or face mortality compared to their non-exercising counterparts.

A Moment of Triumph

"It was one of the most exhilarating moments of my career," said Christopher Booth, an oncology professor at KHSC, reflecting on the day the results were revealed. Emotions ran high—joy, relief, and a profound sense of accomplishment washed over the team as they realized they had uncovered a game-changing scientific discovery.

A Call to Action for Healthcare Providers

Booth hopes these compelling findings will urge healthcare providers to incorporate exercise into standard cancer treatment protocols. "We need to encourage physicians to make exercise a fundamental part of cancer care, just like chemotherapy. It could truly change the landscape of how we approach recovery," he stated.

Future Research and Accessibility

Recognizing the barriers many survivors face when trying to maintain an exercise routine, Booth aims to make physical activity more accessible. Alarmingly, data from the 2005 Canadian Health Community Survey revealed that less than 25% of Canadian cancer patients were physically active.

Looking Ahead: Expanding the Research

The implications of this trial extend beyond colon cancer. Plans are already in motion to explore the impact of exercise on other forms of cancer, including ovarian cancer. Booth's team is now analyzing blood samples collected during the trial to deepen the understanding of how exercise can exert its anti-cancer effects.

A Simple but Powerful Message

As a takeaway for students and cancer survivors alike, Booth emphasizes a universal truth: exercise is essential for better health. "Physical activity is key not only in preventing chronic diseases but also in promoting a vibrant and healthy lifestyle," he stressed. This study is a reminder that staying active can be a powerful ally in the fight against cancer.
