Background: Many epidemiologic studies have found an association between physical
activity and breast cancer risk, although this has not been a consistent finding. Methods …

We conducted a meta-analysis to summarize the evidence from prospective studies
regarding the association between physical activity and breast cancer risk. A comprehensive …

Considerable research interest has been given in the past 25 years to examining the role of
physical activity in breast cancer prevention given the scarcity of modifiable risk factors for …

Breast cancer is the most commonly diagnosed invasive malignancy and the second
leading cause of cancer death in women. This chapter considers epidemiologic evidence …

Objective: It is biologically plausible for physical activity to decrease breast cancer risk;
however, epidemiologic studies have yielded inconsistent findings. We therefore examined …

Breast cancer is the most commonly diagnosed invasive malignancy and the second
leading cause of cancer death in women globally. This review considers epidemiologic …

Purpose/Objectives: To examine the association between physical activity and breast cancer
mortality and recurrence, and to provide an overview of factors related to physical activity …

There is convincing evidence for a decreased risk of breast cancer with increased physical
activity. Uncertainties remain, however, about the role of different types of physical activity on …

Strong evidence exists supporting the effect of lack of physical activity on the risk of
developing breast cancer. However, studies examining the effects of physical activity on …

Physical activity has been hypothesized to reduce breast cancer risk, but an inverse
association has not been consistently reported. In this review, we critically evaluate for …
