Researchers at Newcastle University have shown that physical activity causes the cancer-fighting protein, interleukin-6 (IL-6), to be released into the bloodstream which helps repair the DNA of damaged cells.
The findings, published in the International Journal of Cancer, sheds new light on the importance of moderate activity in the fight against life-threatening illness and could help develop treatments in the future.
Dr Sam Orange, Lecturer in Exercise Physiology at Newcastle University, said: “Previous scientific evidence suggests that more exercise is better for reducing bowel cancer risk as the more physical activity people do, the lower their chances of getting it. Our findings support this idea.
Furthermore, as well as reducing cancer growth, the exercise blood samples reduced the extent of DNA damage, suggesting that physical activity can repair cells to create a genetically stable cell type.
“Our findings are really exciting because they reveal a newly identified mechanism underlying how physical activity reduces bowel cancer risk that is not dependent on weight loss.
“Understanding these mechanisms better could help develop more precise exercise guidelines for cancer prevention. It could also help develop drug treatments that mimic some of the health benefits of exercise.
“Physical activity of any type, and any duration, can improve health and reduce bowel cancer risk but more is always better. People who are sedentary should begin by moving more and look to build physical activity into their daily routines.”
It is estimated that physical activity reduces the risk by approximately 20 per cent.
It can be done by going to the gym, playing sports or through active travel such as walking or biking to work, but also as part of household tasks or work like gardening or cleaning.
