Keep working out, ladies. It may help you prevent getting breast cancer.
Ladies, here is more evidence that physical activity may prevent breast cancer. A prospective study conducted at the Cooper Clinic in Dallas, Texas examined 14,811 women aged 20 to 83 years old with no history of breast cancer. At the beginning of the study each subject received a maximal exercise test to determine their cardiorespiratory fitness. The results of these tests placed them in low, moderate, or high fitness categories. They were followed for an average of 16 years.
Women in the low fitness group were 2.4 times more likely to develop breast cancer when compared to those in the high fitness group!
