The largest study to date shows that physical activity reduces the risk of prostate cancer in half. Scientists have used genetic research methods, which increases the reliability of their data. Scientific work published in the International Journal of Epidemiology.
The study covered 140,000 men over the age of 50. 57% of them developed prostate cancer. Scientists investigated the influence of 22 disease risk factors from the list developed by the World Cancer Research Foundation.
To obtain reliable results, the authors used a genetic research method - Mendeleev's randomization. They tested how often people with certain gene variations (predicting their physical activity, diet, blood lipid and iron levels, and others) develop prostate cancer.
Men with two DNA variations associated with higher physical activity were 51% less likely to develop prostate cancer than those who did not carry the genes. Scientists argue that these results speak to the benefits of any physical activity, not just vigorous exercise.
Dr Sarah Lewis of Bristol Medical School, lead author of the study, said:
“This is the largest study of its kind to date, and uses a relatively new method to complement current observational studies to find out what causes prostate cancer. It shows that physical activity can have a stronger effect than previously thought. We hope this will motivate men to be more active,”
Previous studies have shown that physical activity is associated with a reduced risk of colon cancer, uterine cancer, and breast cancer. But until a new study emerged, evidence for its prophylactic power in prostate cancer was weak.
