A tamoxifen study claims that a combination of chemotherapy and the hormone therapy tamoxifen is more effective than tamoxifen alone in preventing breast cancer.  In the study, a group of researchers from the U.S. and Canada studied 1477 postmenopausal women with early-stage breast cancer.  The women were randomly assigned to one of three study groups.  Group A (361 patients) received tamoxifen alone on a daily basis for five years.  Group B (566 patients) received chemotherapy and tamoxifen for six months, and then completed five years of tamoxifen treatment.  Group C (550 patients) received chemotherapy alone for six months followed by five years of tamoxifen treatment.  All 1477 patients knew which treatment they were receiving.
