A new study published in Journal of Clinical Oncology suggests that the more your exercise, the lower your risk of developing any of seven different types of cancer.
Researchers pooled the data from nine published studies involving more than 750,000 people.
“We found that the recommended amount of physical activity was in fact associated with significantly reduced risk for breast, colon, endometrial, kidney, liver, myeloma and non-Hodgkin lymphoma,” said lead researcher Charles Matthews, a senior investigator at the US National Cancer Institute.
US guidelines recommend 3-5 hours a week of moderate activity for adults, or 1-3 hours a week of vigorous activity. The researchers also found that the harder you exercise during the recommended time, the more you reduce your cancer risk.
Specifically, the risk of colon cancer in men was reduced between 8% for moderate exercise and 14% for vigorous activity. For women’s breast cancer, the reduction ranged from 6% for moderate exercise to 10% for a vigorous work out; for endometrial cancer, from 10% to 18%; kidney cancer, 11% to 17%; myeloma, 14% to 19%; liver cancer 18% to 27%; and non-Hodgkin lymphoma in women, 11% to 18%.
