    Nutritional Impact on Breast Cancer in Menopausal and Post-Menopausal Patients Treated with Aromatase Inhibitors. (PubMed, Cancers (Basel))
    Background/Objectives: Aromatase inhibitors (AIs)-specifically, letrozole, anastrozole and exemestane-represent the current gold standard for patients with estrogen-receptor-positive breast cancer (ER + BC). The data presented herein are derived from in vitro, in silico, and animal model studies and await validation in large patient cohorts. Nevertheless, these findings pave the way for future research to elucidate these molecular phenomena in humans and to establish clinically significant conclusions for ER + BC patients.
