Hormone therapy raises breast cancer deaths: study
(Reuters) - Women
who took hormone replacement pills had more advanced breast cancers and
were more likely to die from them than women who took a dummy pill,
raising new concerns about the commonly prescribed drugs, U.S.
researchers said on Tuesday.The study, published in the Journal of the American Medical Association, is the first to report more breast cancer deaths among women taking hormone replacement therapy.
And it contradicts prior studies that suggest women taking the drugs had less aggressive, easier-to-treat breast cancers.
"As opposed to the prevailing thought of two years ago, that cancers associated with estrogen plus progesterone would be favorable and not much of a problem, we are actually showing they are associated with an increased risk of death from breast cancer," Dr. Rowan Chlebowski of the Los Angeles Biomedical Research Institute, who led the study, said in a telephone interview.
