Physical activity linked to reduced risk of several types of cancer

Colon cancer, breast cancer, uterine cancer, liver cancer, non-Hodgkin's lymphoma, and myeloma are less common in physically active people. In total, scientists in their review analyzed the incidence of 15 types of cancer.

Scientists have confirmed that physically active people are less likely to develop certain types of cancer. A study report in which they analyzed data on 750,000 adults is published in the Journal of Clinical Oncology.

Colon cancer, breast cancer, uterine cancer, liver cancer, non-Hodgkin's lymphoma, and myeloma are less common in physically active people. In total, scientists in their review analyzed the incidence of 15 types of cancer.

Previous studies have shown a similar effect of physical activity on cancer risk. New scientific work shows this connection in more detail.

The World Organization's recommended level of physical activity is 150 minutes of moderate-intensity aerobic exercise or 75 minutes of vigorous exercise per week. In people who adhered to this level of activity, according to the study, breast cancer developed 6-10% less often, and the risk of liver cancer was reduced by 18-27%.

Reduced risk for some cancers has been associated with exercise that exceeds current guidelines. The authors speculate that this "may reflect important biological mechanisms that underlie various types of cancer."

When scientists took BMI into account in their calculations, the link between exercise and uterine cancer was no longer found. In addition, the effect of exercise on the risk of non-Hodgkin's lymphoma was found only in women and on colon cancer only in men.

The information about physical activity that the scientists analyzed was obtained from the words of the study participants themselves. Scientists caution that the study does not show that exercise is a direct cause of lower cancer risk: other factors may have played a role.
