Abstract
Observational studies associate obesity and physical inactivity with adverse breast cancer outcome. Whether weight loss/maintenance or increase in physical activity after diagnosis can improve breast cancer outcome is not established. While alcohol use increases breast cancer risk, the role of alcohol in altering breast cancer outcome is not established. Only two full-scale randomized clinical trials have evaluated lifestyle change in early-stage, resected breast cancer and they provide mixed results. Despite strong preclinical evidence and identified potential mediating factors, only one full-scale lifestyle intervention trial is currently ongoing, SUCCESS-C, which will evaluate a program of weight reduction and increased physical activity in an adjuvant setting. On the basisi of current evidence, weight loss/maintenance and physical activity increase/maintenance can reasonably be recommended for breast cancer patients with early-stage disease. However, the strength of the recommendation awaits definitive randomized clinical trial evidence.
