Breast Cancer Risk Factor Drops With Decline in HRT

A decline in hormone replacement therapy may be causing a decrease in the rates of a known risk factor for breast cancer, according to researchers. A recent study published in the November issue of Cancer Epidemiology, Biomarkers & Prevention has shown that the rate of a benign breast condition known as atypical ductal hyperplasia has decreased along with the decline in hormone replacement therapy (HRT) seen since 2002. Atypical ductal hyperplasia is a known risk factor for developing breast cancer, and is suspected of being a breast cancer precursor.
