I just today saw my oncologist. I had my surgery 8/2019 and have been on Anastrozole almost 2 years. I am just starting to have joint aches. The hot flashes are nothing new for me. I'm 68. When I inquired about the level of my estrogen in relation to how the med was working, his response was that he takes it for granted in is working. Estrogen is 'suppose' to be sucked out of my body. He said he would have to see if there was an estrogen test. I am pretty well put off with him. Any opinions. What test should I be asking my doctor for to see if the Anastrozole is actually working. I would like to know if i could take it say every other day to keep my estrogen low or do I REALLY need it every day. Just because the protocol is 1 pill a day for everyone doesn't make it the right dosage. Thanks for your post.
