Runners are 25% less likely to develop breast cancer says a new study

Many of us know of someone who suffered through breast cancer. It is a horrible disease process that does not have a credible explanation for why it occurs (although certain genes increase the risk markedly such as Brac1 and Brac2). If you are an avid runner, Runners World reports on a new study that shows that running decreases the risk of development of the disease by 25%. The takeaway on this is running decreases your risk of breast cancer among its many other benefits.

Runners at Less Risk of Dying From Breast Cancer

41% lower risk even in women averaging a few miles a week.

By Scott Douglas Published December 10, 2013

Regular physical activity is known to reduce breast cancer risk by about 25%. This estimate is based on studies that recorded the number of hours per week women spent exercising and doing other physical activities. New results from the National Runners’ and Walkers’ Health Studies suggest that the benefits of meeting current government exercise recommendations may be even greater, with small amounts of regular exercise potentially lower the risk of dying from breast cancer by more than 40%.

The research is the latest big-data publication by Paul Williams, Ph.D., whose work has shown the health benefits of running and walking in areas such as hypertension, all forms of cancer, and even cataracts. For this study, published in the online journal PLoS One, Williams looked at breast cancer mortality in 79,124 women during the 11 years following their baseline survey. None of the women had a history of breast cancer before entering the study. The women reported the distances they walked or ran each week.

During the study’s 11 years, 111 women died from breast cancer. Those who met the current exercise recommendations were at 41.5 % lower risk for breast cancer mortality compared to those who fell short of the recommendations.
