In this article, we review recent findings related to estrogenexposure and the risk of breast cancer, the mechanisms thatmay be involved, and the clinical implications of these findings.The weight of evidence indicates that exposure to estrogen isan important determinant of the risk of breast cancer. The mechanismsof carcinogenesis in the breast caused by estrogen include themetabolism of estrogen to genotoxic, mutagenic metabolites andthe stimulation of tissue growth. Together, these processescause initiation, promotion, and progression of carcinogenesis.Insight into the mechanisms of the causation of cancer by estrogenwill identify determinants of susceptibility . . .
