Noel Weiss, MD, DrPH

As a cancer epidemiologist, Dr. Noel Weiss assesses the biological, behavioral and environmental factors that play a role in the development of cancer and in the variation in outcomes among individuals diagnosed with cancer. One of his major areas of research is the link between estrogen-only postmenopausal hormone therapy and endometrial cancer (cancer of the uterine lining). His early work documented the rapidly rising incidence of endometrial cancer in the U.S. among American postmenopausal women that followed an increase in the use of non-contraceptive estrogens. His observation, combined with the results of other related studies, led to the development of alternate means of administering estrogens (combined estrogen-plus-progesterone hormone therapy) that did not give rise to this adverse effect. His other research interests include assessing the effectiveness of various cancer-screening tools in reducing cancer deaths.
