While researchers have been hesitant to look at the long-term effects of estrogen blockers on human subjects, researchers from Georgetown Lombardi Comprehensive Cancer Center along with other institutes were able to use a computer model to assess the efficacy of estrogen-blocking treatment on a population after a five-year use.

Through this computer model, the researchers were able to quantify the results of a regimen of five years of estrogen-blocking treatment along with annual screening. They compared the outcome to a control group that received only annual screenings, but no treatment. The full report can be found in the Journal of Clinical Oncology. What they found was that the group that received an estrogen-blocking treatment called Tamoxifen, saw a reduced risk of invasive breast cancer and mortality by 40 to 57 percent compared to those without treatment.
