Mean 24-hr growth hormone, luteinizing hormone, follicle-stimulating hormone, estradiol, and progesterone concentrations determined preoperatively in 16 women with benign breast masses and 17 patients with breast cancer were similar to those levels found in 25 age- and weight-matched control subjects. Mean 24-hr testosterone levels, however, were significantly elevated in women with breast cancer evaluated in the luteal phase of their cycles and were normal in postmenopausal breast cancer women. In addition, serum thyroid-stimulating hormone, thyroxine, cholesterol, and triglyceride levels were normal in these subjects. Plasma cortisols and urinary 17-hydroxysteroid excretion tended to be higher in both the benign and malignant breast disease group and probably reflected preoperative anxiety. Hence, we have found normal concentrations of a variety of endocrine and other biochemical agents that can stimulate breast tissue growth and/or have been previously reported to be disordered in women with breast cancer.
