Our cross-sectional results among postmenopausal Asian control women suggest elevated concentrations of estrone and androgens (total testosterone, androstenedione, and DHEAS) and are qualitatively similar to the results reported by the Endogenous Hormones and Breast Cancer Collaborate Group, which pooled cross-sectional data from more than 6,000 postmenopausal women, almost all of whom were of European ancestry [34]. The gene discussed is SULT2A1; the disease is breast carcinoma.
