Physical Activity Levels, Obesity and Breast Cancer

Research also reveals ethnic and racial disparities.

Obesity and breast cancer

Exercise programs may contribute to reducing not only obesity but also breast cancer risks. While death rates from breast cancer have dropped in the U.S. in the past 20 years, the incidence rate has increased significantly, according to a study of more than 4 million breast cancer patients published in JAMA Network Open (2022; 5 [6], e2216958).

Among the findings were significant ethnic and racial disparities, both in incidence rates and survivorship. The good news is that increased screening is linked with decreased mortality. Researchers noted an association between higher rates of breast cancer with obesity and physical inactivity and recommend more strategies to increase movement, reduce obesity and improve access to screening.
