What's Happening?
Researchers at Newcastle University have discovered that just 10 minutes of intense exercise can significantly impact cancer cell growth. The study, published in the International Journal of Cancer, reveals
that short bursts of vigorous physical activity can alter the molecular composition of the bloodstream, which in turn suppresses bowel cancer cell growth and enhances DNA repair. The research involved 30 overweight or obese volunteers aged 50 to 78, who participated in a brief cycling test. Blood samples taken post-exercise showed increased levels of molecules that reduce inflammation and support healthy blood vessels. These molecules also triggered genetic changes in cancer cells, affecting over 1,300 genes related to DNA repair and cancer cell growth.
Why It's Important?
This study underscores the potential of exercise as a non-invasive method to aid in cancer prevention and treatment. By demonstrating that even a single session of exercise can send beneficial molecular signals throughout the body, the research highlights a simple yet effective strategy to reduce cancer risk. The findings suggest that regular physical activity could lower bowel cancer risk by approximately 20%. This has significant implications for public health, as it provides an accessible means for individuals to contribute to their own cancer prevention efforts. Moreover, the study opens avenues for developing new therapies that mimic the biological effects of exercise, potentially enhancing cancer treatment outcomes.
What's Next?
The research team plans to investigate whether repeated exercise sessions can lead to sustained biological changes. They also aim to explore how the effects of exercise interact with conventional cancer treatments like chemotherapy and radiotherapy. These future studies could further elucidate the role of exercise in cancer management and potentially lead to integrated treatment approaches that combine physical activity with medical therapies.
