Tamoxifen was not even considered for me because there is an indication for
blood clots while on it. Femara does not have that indication, however, the
clots kept coming while I was on it. It also caused severe bone pain. A little more than a year ago, I switched to Aromasin, and things have dramatically improved. If her cancer is estrogen receptor positive as well as being slow growing, then the hormone therapies like Femara, Aromasin, Arimidex, etc.
