    Abstract

    The Impact of Obesity and Adipokines on Breast and Gynecologic Malignancies

    The authors organize and present the literature from the last five years investigating the mechanisms and implications of adipokine signaling in breast, endometrial, and ovarian cancers with a special focus on leptin and adiponectin.
