Exercise and Breast Cancer Risk

Regular exercise has been linked to a reduced risk of developing breast cancer, possibly by helping to regulate hormones, strengthen the immune system, and control body weight. Physical activity can lower levels of estrogen and other hormones associated with breast cancer growth. It also helps maintain a healthy weight, which is important because excess body fat can increase risk. Engaging in consistent, moderate exercise—such as walking, cycling, or swimming—most days of the week is recommended as a proactive way to support breast health and overall well-being.
