Experts from the American Society of Clinical Oncology advise that a healthy lifestyle can reduce a woman’s risk for breast cancer nearly 25%, even if she has a family history of the disease. Previous research has associated the following lifestyle factors with a lower risk of breast cancer diagnosis: maintaining a healthy weight, performing at least 150 minutes of moderate-to-vigorous physical activity per week, limiting alcohol consumption, not smoking, and eating a healthy diet.
