One of the anti-estrogen drugs,
Aromasin, is in the same family as
Femara. These drugs are very new and thus far had been used only with breast cancer patients. Aromasin is now in clinical trials for ovarian cancer recurrence.
I did not wait to see the outcome of the trials; I got a prescription for it and have been on it for almost a year. It cuts the estrogen production in the body, so that if your cancer is estrogen receptive, it's less likely that it will recur.
