Just 10 minutes of exercise can trigger powerful anti-cancer effects

As people return to gyms or start new fitness routines in the new year, new research suggests that even a short burst of intense exercise could play a role in protecting against cancer. Scientists report that as little as 10 minutes of hard physical activity may help slow cancer growth.
The study found that brief, vigorous exercise quickly changes the mix of molecules circulating in the bloodstream. These rapid shifts appear to suppress bowel cancer cell growth while also speeding up the repair of damaged DNA.
How Exercise Changes the Bloodstream
Researchers at Newcastle University discovered that exercise raises the levels of several small molecules in the blood. Many of these molecules are known to reduce inflammation, support healthy blood vessels, and improve metabolism.
When scientists exposed bowel cancer cells in the lab to blood containing these exercise-driven molecules, they observed widespread genetic changes. More than 1,300 genes shifted their activity, including genes involved in DNA repair, energy production, and cancer cell growth.
Published in the International Journal of Cancer, the findings help clarify how physical activity may lower bowel cancer risk. The research shows that exercise sends molecular signals through the bloodstream that influence genes controlling tumor growth and genetic stability.
The results add to growing evidence that staying physically active is an important part of cancer prevention.
New Possibilities for Cancer Treatment
Dr. Sam Orange, Senior Lecturer in Clinical Exercise Physiology at Newcastle University and lead author of the study, said: "What's remarkable is that exercise doesn't just benefit healthy tissues, it sends powerful signals through the bloodstream that can directly influence thousands of genes in cancer cells.
