A major international trial shows that a structured, coach-led exercise program after colon cancer treatment can lower recurrence risk and reduce overall mortality. Presented at ASCO 2025 and published in The New England Journal of Medicine, the study suggests exercise can match—or even exceed—the benefits of certain cancer drugs, while offering the well-known perks of physical activity. The findings have immediate implications for cancer survivors in Thailand as well as globally.
Data from 889 colon cancer patients across the United States, United Kingdom, Australia, France, Canada, and Israel indicate that a personalized exercise plan reduced the risk of cancer returning or a new cancer by 28 percent and lowered death from any cause by 37 percent over eight years, compared with standard lifestyle advice. These results arrived from a rigorously designed randomized controlled trial, moving beyond earlier observational studies and establishing a direct link between activity and survival.
For Thai readers, the message is particularly timely. Cancer remains a leading cause of death in Thailand, with colorectal and other cancers rising among aging populations in both cities and rural communities. Survivorship is increasingly important as early detection and treatment improve. The prospect of a clinically endorsed exercise program offers a practical, low-cost path to better long-term health, potentially reducing recurrence and secondary health risks for Thai patients.
The trial used a three-year program combining monthly or bi-monthly sessions with a personal trainer and individualized goals for moderate activities such as brisk walking, cycling, or culturally familiar options like community aerobics or river kayaking. Importantly, the activities were adaptable to personal preferences and local settings—from Muay Thai-inspired routines to park workouts in Bangkok and village-based physical activity in rural areas.
Experts emphasize the strength of the evidence. ASCO’s chief medical officer notes that the benefit is substantial and, in many cases, comparable to drug therapies, but without significant toxicity or cost. Researchers from Queen’s University and collaborating cancer organizations describe exercise as accessible, scalable, and genuinely empowering for patients during recovery.
In practical terms, the recommended target is about 150–180 minutes of moderate activity per week, equivalent to three or four half-hour sessions. The focus is on consistency and sustainability rather than intensity. Patients reporting improvements in mood, energy, sleep, and overall quality of life align with the broader benefits of staying active during and after treatment.
Biologically, regular activity helps by reducing systemic inflammation, improving insulin sensitivity, and boosting immune surveillance. It also supports heart and brain health—areas of concern for cancer survivors who may face long-term effects from treatment. Data from international health bodies and exercise-oncology groups reinforce the potential for exercise to become a standard component of cancer care in Thailand and beyond.
For Thai clinicians and policymakers, the study supports integrating structured exercise coaching into survivorship care. Hospitals and rehabilitation centers can expand access through partnerships with physical therapists, certified trainers, and community or temple-based wellness programs. This approach aligns with Thai values of holistic well-being and social harmony, while providing a practical framework for national cancer care improvements.
Historically, access to post-treatment rehabilitation in Thailand has varied by region. The new evidence provides a clear, culturally adaptable path to combine movement with traditional wellness practices—such as temple walks, guided garden activities, or community dance—that respect local customs while meeting medical guidelines for duration and intensity.
Looking ahead, researchers advocate for similar trials across other cancer types, including breast and prostate cancers, to determine whether the benefits extend broadly. The ultimate aim is to embed coached, culturally tailored exercise prescriptions into standard care, supported by insurers and government health programs. In Thailand, this could drive broader training for healthcare workers, expansion of community-based exercise programs, and enhanced coverage for rehabilitation services.
For patients and families in Thailand, the core takeaway is empowering: regular, personalized exercise can meaningfully reduce recurrence risk and improve longevity, alongside conventional therapies. Always consult a healthcare professional before starting any new activity, especially during or after intensive cancer treatment, to ensure safety and appropriateness.
Hospitals and health authorities in Thailand are encouraged to develop and fund structured survivorship programs that include exercise coaching, with a focus on accessibility in urban centers and rural communities alike. Community networks can support implementation by organizing group walks, activity sessions, and culturally resonant physical activities that promote lasting health.
In sum, the evidence is strong and globally endorsed: movement is a powerful medicine for cancer survivors. It’s time to lace up, commit to regular activity, and participate actively in recovery, guided by medical advice and local cultures.
