I am so sorry this has happened. It is not because you didn’t take AI. I do hope that women who can tolerate them will at least give them a try. If for no other reason to prevent this kind of second guessing. There are many women who never take them and never see their cancer again. The contrary is also true. I took them and it still came back. Don’t put yourself through that kind of agony. This is absolutely not your fault!
Have your doctors discussed next steps yet?
