Does estrogen cause cancer?
This week's question was from Melissa in Reedley: Does estrogen cause cancer?
Jeff: That is a complex question and there are still multiple studies trying to determine the exact cause of breast cancer. Although estrogen has been put on the list of carcinogenic chemicals, not all forms of estrogen cause cancer and further research is trying to determine if there is a separate metabolic pathway that is part of or the cause of breast cancer. Certainly, a link between breast cancer and estrogen has been shown, but more research needs to be done to get a better understanding of the relationship between estrogen and breast cancer.
