hormone replacement therapy can raise the risk of an uncommon type of breast cancer. Maggie Fox of Reuters reports:According to new research,
They found women who took combined estrogen/progestin hormone-replacement therapy for three years or more had four times the usual risk of lobular breast cancer.
Their study, published in the January issue of Cancer Epidemiology, Biomarkers and Prevention, is one of dozens trying to paint a clearer picture of what dangers might come from taking HRT to treat menopause symptoms.
"Previous research indicated that five or more years of combined hormone-therapy use was necessary to increase overall breast-cancer risk," Dr. Christopher Li of the Fred Hutchinson Cancer Research Center, who led the study, said in a statement.
