Women who exercise regularly during their younger years are 23 percent less likely to develop breast cancer as adults, according to a new study conducted by researchers from the Washington University School of Medicine in St. Louis and published in the Journal of the National Cancer Institute.
Researchers questioned 65,000 female nurses between the ages of 24 and 42 about their exercise histories back to the age of 12, then followed them for six years. Women who had engaged in at least three hours and 15 minutes of vigorous activity, such as running, each week between the ages of 12 and 22 were 23 percent less likely to develop cancer during the study period than women who had not exercised that much. The same protective benefit seemed to accrue to women who engaged in 13 hours per week of moderate exercise – such as walking – instead. CLICK HERE to read the rest of this story on Natural News.
