When studies warned hormone replacement therapy could lead to a higher risk of breast cancer, millions of women stopped taking them. A new report shows they might have made the right decision.
A new study shows U.S. breast cancer rates dropped seven percent in 2003 and strongly suggests that the reason is less hormone use.
About 14,000 fewer women were diagnosed with the disease, almost all 50 to 69-year-olds.
Experts believe we're seeing this trend because many women stopped using hormone replacement therapy to prevent hot flashes. Researchers said they looked for a similar drop in other cancers, which could have indicated something other than the hormones but they didn't find anything.
