Fitness News: Vigorous Exercise Lowers Breast Cancer Risk
Today is the beginning of National Breast Cancer Awareness Month. Every October breast cancer charities across the globe campaign to help build awareness and raise research funds for the prevention and cure of breast cancer.
A new study further supports the premise that fitness after menopause can significantly reduce the risk of breast cancer. Previous studies have linked exercise to protection against breast cancer, but this was among the first to look at the importance of different kinds of exercise at various stages of life.
Over 110,000 post menopausal women were asked to rate their level of physical activity at ages 15-18, 19-29, 35-39, and in the past 10 years. It was found, over 6.6 years of follow up, that women who engaged in more than 7 hours per week of moderate-to-vigorous exercise for the last ten years were 16% less likely to develop breast cancer than those who were inactive. However, no link was observed between breast cancer risk and physical activity in women who were active at a younger age.
"Our findings could help inform the mechanisms of the physical activity-breast cancer relationship. With breast cancer still claiming so many lives, all the information of potential preventive measures we can get is vital," says Dr. Tricia M Peters from the U.S. National Cancer Institute, Bethesda, Maryland, who headed up an international team of researchers.
