Hormones after menopause may cause deadlier cancer

October 19, 2010

A new study in the Journal of the American Medical Association says HRT not only increases the risk of breast cancer, it makes it more likely to be advanced and deadly.

In the study, those on combination hormone replacement therapy were more likely to have invasive breast cancer, and those cancers were more likely to be lymph node positive.

Combination HRT is still used in short intervals.

In an editorial in the same journal, researchers said they did not know whether the short-term use of HRT is safe.
