Reduce your breast cancer risk with exerciseThe Breast Cancer Site

Physical activity has been reported to reduce breast cancer risk. However these studies have not adequately addressed relevant factors such as duration, intensity, and optimal time for exercise note the authors of a new study. Researchers affiliated with the University of North Carolina (Chapel Hill, NC), Columbia University (New York, NY), and Mount Sinai University (New York, NY) published a study evaluating factors related to exercise on June 25 in the journal Cancer.
The authors noted that, although physical activity reduces breast cancer risk, issues critical to providing clear public health messages remain to be elucidated. These include the minimum duration and intensity necessary for risk reduction and the optimal time period for occurrence, as well as subgroup effects, particularly with regard to tumor heterogeneity (type of tumor) and body size.
