Physical activity among patients with breast cancer receiving aromatase inhibitors is associated with bone health: a cross-sectional observational study

To examine the association of physical activity (PA) with bone health among patients with breast cancer receiving adjuvant aromatase inhibitor (AI) treatment. In this single-center observational study, we enrolled postmenopausal women with primary hormone receptor-positive breast cancer who were receiving adjuvant AI treatment.
