Holistic Health Show with Carl Helvie logoA new study published in Cancer Epidemiology, Biomarkers & Prevention concluded that post menopausal women who undertook regular physical activity over the past 4 years that was equivalent to 4 hours of walking per week (cycling or other sports for 2 hours/week)  had a 10 percent lower risk for invasive breast cancer compared with women who exercised less during those four years.

Data was analyzed from over 59,300 post menopausal women in France. The mean duration of follow up was 8.5 years during which time 2,155 women were diagnosed with a first primary invasive breast cancer. The total amount of self-reported physical activity per week was calculated and the reduction in invasive breast cancer among those having a higher amount of physical activity was independent of the body mass index, weight gain, waist circumference,  and the level of activity from 5 to 9 years earlier.
