Androgens are involved in the development of breast cancer, although the mechanisms remain unclear. To further investigate androgens in breast cancer, we examined the relations between serum testosterone and age, body mass index (BMI), tumor size, histologic type, grade, axillary node involvement, estrogen receptor status, progesterone receptor status, and HER2 overexpression in a cross-sectional study of 592 postmenopausal breast cancer patients. Mean testosterone differences according to categories of patient and tumor characteristics were assayed by Fisher's or Kruskall-Wallis test as appropriate; adjusted odds ratios (OR) of having a tumor characteristic by testosterone tertiles were estimated by logistic regression. Testosterone concentrations were significantly higher in women with BMI ≥30 versus BMI
