Key Points Question Is adherence to cancer prevention lifestyle recommendations before, during, and after chemotherapy associated with disease recurrence and mortality in patients with high-risk breast cancer? Findings In this prospective cohort study of 1340 patients with high-risk breast cancer, strongest adherence to the American Cancer Society and American Institute of Cancer Research prevention recommendations was associated with a 37% reduced hazard of breast cancer recurrence and a 58% reduced hazard of mortality. Meaning These findings suggest that education and implementation strategies to help patients adhere to cancer prevention recommendations throughout the cancer care continuum may be warranted in breast cancer.
