Mehmet Oz, MD, Cardiology, answeredThe first molecular target was found on the surface of certain breast cancer cells. A region on the cell's membrane had a particular affinity for estrogen. Estrogen can fuel the growth of some types of breast cancer but when the receptor was blocked, the cells were less likely to grow out of control. Several drugs have been specifically designed to hook into the estrogen receptor's spot, leaving estrogen out of the lurch.
