Exercise More Effective Than Medicine in Preventing Cancer Recurrence: Study

A groundbreaking international study has revealed that structured physical exercise after cancer treatment can significantly reduce the risk of death and cancer recurrence—potentially proving more effective than medication. Researchers highlight that exercise carries no side effects and offers long-term benefits.

The 14-year-long study involved 889 colon cancer patients from the United States, United Kingdom, Canada, Australia, France, and Israel. Half of the participants were enrolled in a supervised exercise program, while the other half received only a basic health advice booklet.

Results showed that patients who engaged in regular, guided exercise experienced a 37% reduction in mortality and a 28% lower risk of cancer recurrence. These findings were presented at the American Society of Clinical Oncology’s (ASCO) Annual Meeting in Chicago and published in the New England Journal of Medicine.

Dr. Julie Gralow, ASCO’s Chief Medical Officer, emphasized the significance of the research: “This is among the highest level of evidence we’ve ever had. In my opinion, exercise is not just as good as a drug—it’s better. It’s affordable, free of side effects, and delivers lasting impact.”

Previously, doctors advised cancer patients to avoid exertion during treatment. However, this study signals a major shift in that perspective. Experts now advocate for integrating physical activity into both treatment and recovery phases, calling it a vital and effective component of modern cancer care.
