There have been several studies which have conclusively pointed to the protective effects of exercise upon a woman's risk for breast cancer. It is clear from these studies that the effects of regular exercise are greatest when women begin in their early teens, perhaps because it is often maintained throughout the woman's life. Most importantly however, is that these studies have also determined that it is never too late to start exercising and effectively lowering one's risk for breast cancer. Even adult women, who have never exercised, can significantly reduce their risk if they begin to incorporate regular exercise into their routine . It is still unclear the exact mechanisms which seem to contribute to the protective effect of exercise on the body.
Some studies indicate that exercise regulates hormone levels.
Other studies link exercise to the lowering of body fat. Both of these findings are quite significant and can account for the dramatic impact that exercise seems to have on one's risk for breast cancer. There are specific ways to evaluate your percentage. It also showed that it was never too late to start . A Harvard study determined that women who are sedentary have twice the risk for developing breast cancer as compared to women who do exercise.
