Obesity and post-diagnosis weight gain in breast cancer patients are associated with significantly increased risks of disease recurrence and mortality.
Maintaining a healthy weight or losing weight after a breast cancer diagnosis is clinically important. Evidence shows that being overweight or gaining weight after diagnosis increases the risk of the cancer returning and reduces survival. While specific weight loss protocols for breast cancer are still being finalized, managing weight through diet and activity is recommended to potentially improve outcomes.
women with breast cancer who are overweight or gain weight after diagnosis are found to be at greater risk for breast cancer recurrence and death compared with lighter women.
Why this rating
Based on a meta-analysis of 34 studies (29,460 women) and multiple prospective cohorts, though definitive intervention trials are lacking.
