Retrospective cohort study of association of resistance training and lymphedema in breast cancer survivors

Lymphedema is a common treatment-related adverse effect among breast cancer survivors. A retrospective cohort study of 115 breast cancer survivors found that intense resistance training was not associated with an increase in lymphedema symptoms. Bioimpedance analysis revealed significant reductions in extracellular water and improved fluid balance, suggesting a potential therapeutic benefit. The authors conclude that these results suggest safety and potential benefits of intense resistance training for breast cancer survivors, challenging outdated restrictions on strength training.
