It has long been thought that women who take hormone therapy are prone to develop breast cancer.  This study looked at 1,072 patients and found that the use of Hormone Replacement Therapy that was started and continued before the diagnosis of breast cancer resulted in more favorable primary tumors, with a lower incidence of recurrences and a better overall survival rate.  That is, while women still got breast cancer (at baseline rates, not increased risk) when they did get tumors, they were less aggressive and had more favorable outcomes.
