Exercise and Cancer: How Physical Activity May Reduce Progression and Death Risk

A new study published in the British Journal of Sports Medicine highlights the potential benefits of exercise in lowering cancer progression and mortality risks. Conducted in South Africa, the research analyzed data from over 28,000 participants with stage 1 cancers, showing that moderate to high physical activity before diagnosis was associated with a 27% lower likelihood of cancer progression and a 47% reduction in death from any cause.

This article examines the study’s findings, the role of exercise in cancer management, and the implications for those affected by cancer.

The Study: How Exercise Impacts Cancer Progression

Researchers focused on participants enrolled in a health program that tracked physical activity using fitness devices and gym attendance. Dividing participants into three groups—no activity, low activity, and moderate to high activity—they discovered a clear link between pre-diagnosis exercise levels and improved outcomes.

For those in the moderate to high activity group, the benefits were significant: better odds of preventing cancer progression and improved overall survival rates. The results were consistent across various cancer types, including breast and prostate cancer, two of the most common forms studied.

Why Physical Activity Matters in Cancer Management

The connection between exercise and cancer outcomes is rooted in its impact on inflammation, immune function, and overall physical health. Moderate activity boosts the body’s ability to repair damage, reduces systemic inflammation, and improves energy levels—all critical factors when managing cancer and its treatments.

Additionally, exercise helps reduce comorbidities like obesity and cardiovascular disease, which can complicate cancer recovery. This study adds to growing evidence that physical activity isn’t just a preventative measure—it’s a valuable component of holistic cancer care.

Key Findings and Limitations of the Study

While the research provides strong evidence of the benefits of physical activity, it stops short of proving a causal relationship. Factors such as self-reported activity levels and unadjusted variables like smoking or diet may influence the results.

Still, the findings are promising: individuals with moderate to high physical activity had a better chance of surviving two years post-diagnosis and lower rates of cancer progression compared to those who were inactive.

Incorporating Exercise into Cancer Care Plans

For those diagnosed with cancer, adopting an exercise routine should be personalized and approved by healthcare providers. Activities like walking, swimming, or yoga can provide gentle but effective physical activity, particularly for patients undergoing treatment.

This study encourages oncologists and patients to discuss exercise as part of a comprehensive care plan, highlighting its potential to improve outcomes and enhance quality of life.

The Takeaway: A Path Toward Better Outcomes

While more research is needed, the study reinforces the idea that physical activity plays a significant role in cancer management. By incorporating exercise into daily routines, individuals may improve their odds of survival and reduce the likelihood of cancer progression.

In conclusion, exercise isn’t just about staying fit—it’s a powerful tool for improving health outcomes and navigating life after a cancer diagnosis.
