Since so many women are living beyond 65 years it's amazing that they dismiss us or push us off the map. You have to do your own study I'm afraid. With me, I have decided to forgo Anastrozole and letrozole-'I only took that for a week- and I read that Anastrozole sticks with you with side effects for longer than you think. I have been over a month now without it and feel great, but I am shocked that I am still having some hot flashes. They are minor but still inconvenient. Now that I'll be going without any medication until May 14 which is my next big exam. I will be interested in seeing if they have enlarged or if they have continued to shrink. I considered this a test. My lumpectomy is coming up May 24th and since cancer was found in both breasts I will probably have a lumpectomy in both breasts. However, after being on Anastrozole for 90 days my surgeon and nurses were absolutely shocked at the results of shrinkage. The next two weeks started by 90 days on a new prescription of anastrazole and I fell apart. Anyway, I'll let you know if since anastrazole was stopped and I will have gone a month and a half without it it would be interesting to know if I continue to shrink the tumor or if it grew. I will let you know.
