A Single Workout Could Slash Cancer Risk, New Research Suggests
A 20-30% reduction in cancer growth – achievable with just one bout of exercise. That’s the startling potential revealed by new research from Edith Cowan University (ECU), challenging conventional wisdom about cancer treatment and prevention. The study isn’t advocating for replacing traditional therapies, but rather positioning exercise as a powerful, readily available adjunct, potentially revolutionizing how we approach this devastating disease.
The Power of Myokines: Exercise as Medicine
ECU PhD student Francesco Bettariga’s research centers on exercise and cancer, specifically the role of myokines. These proteins, released by muscles during physical activity, possess potent anti-cancer properties. Bettariga’s work with breast cancer survivors demonstrated that both resistance training and high-intensity interval training (HIIT) significantly increased myokine levels, even in individuals whose bodies were impacted by cancer and its treatment. “The results from this study are excellent motivators to add exercise as standard care in the treatment of cancer,” Bettariga stated.
This isn’t simply about feeling good after a workout. The increase in myokines directly impacts cancer cell proliferation. While elevated myokine levels are common in healthy individuals post-exercise, the study’s significance lies in proving the same benefits are attainable for cancer survivors – a population often facing physical limitations and systemic inflammation. This finding underscores the adaptability of the human body and the potential for targeted interventions to bolster its natural defenses.
Beyond a Single Bout: The Inflammation Connection
Bettariga’s research didn’t stop at a single workout. He further investigated the long-term impact of consistent exercise on body composition and, crucially, inflammation. Chronic inflammation is a known driver of cancer progression, recurrence, and mortality, inhibiting immune function and creating a fertile ground for tumor growth.
The Lean Mass Advantage
The research revealed a clear correlation: reducing fat mass and increasing lean muscle mass through consistent exercise effectively lowered inflammation levels in breast cancer survivors. This isn’t about crash dieting; Bettariga stresses the importance of building or preserving muscle. “You never want to reduce your weight without exercising, because you need to build or preserve muscle mass and produce these chemicals that you can’t do through just diet alone.” The muscle itself is the engine driving the production of these beneficial myokines and the regulation of inflammatory markers.
This highlights a critical distinction: exercise isn’t just about weight loss; it’s about body recomposition. Shifting the focus from simply shedding pounds to building a stronger, leaner physique unlocks a cascade of physiological benefits that directly combat cancer’s insidious mechanisms.

Future Trends: Personalized Exercise Oncology
The implications of this research extend far beyond breast cancer. While the initial study focused on survivors, the underlying principles – the power of myokines and the importance of managing inflammation – are likely applicable to a wide range of cancers. We’re on the cusp of a new era in cancer care: personalized exercise oncology.
Imagine a future where exercise prescriptions are tailored to an individual’s cancer type, treatment plan, and genetic profile. Wearable technology could monitor myokine levels in real-time, providing feedback and optimizing workout intensity. AI-powered algorithms could predict an individual’s response to different exercise modalities, maximizing therapeutic benefits and minimizing risk. This isn’t science fiction; the foundational research is happening now.
Furthermore, research will likely expand to explore the optimal “dosage” of exercise – the ideal frequency, intensity, and duration needed to achieve maximal anti-cancer effects. Investigating the synergistic effects of combining exercise with other therapies, such as immunotherapy and chemotherapy, will also be crucial. The long-term impact of sustained myokine elevation on cancer recurrence remains a key area for future investigation.
