Multiple plasma-hormone concentrations were measured in sequential plasma-samples from six women with breast cancer and were compared to concentrations in six control women matched for age, years since menopause, and parity. All hormone concentrations in all the women studied were within normal limits. However, within the normal range the plasma-testosterone concentrations in each cancer patient were significantly higher than in each matched control.
