Breast cancer researcher Elwood Jensen has died, reports The New York Times. He was 92. In his work, Jensen showed that steroid hormones bind to specific receptors within cells and later developed a test to determine whether breast cancer cells contained estrogen receptors. Estrogen-receptor-positive breast cancers, the Times notes, can be treated with Tamoxifen or surgical removal of the ovaries to limit estrogen in the patient's body and treat the disease. Jensen received the Albert Lasker Basic Medical Research Award in 2004 along with Pierre Chambon and Ronald Evans for their work on steroid hormone receptors. Jensen's research "also led to the development of drugs that can enhance or inhibit the effects of hormones. Such drugs are used to treat prostate and other cancers," the Times adds.
