Glad you caught the cancer early. I had a stage 0 LCIS which 2 years later became a Stage One. Because the Lobular is trickier, I opted to have a bi lateral mastectomy so I wouldn't have to go through all the constant testing and worry. All that said……I tried the aromatase drugs (Letrozole and Arimidex) and had ALL the side effects (just lucky I guess) and opted not to use them……at Stage 0 and again at Stage 1. BUT, I think I am the exception. I can't tolerate most drugs. There are lots of people who do tolerate them pretty well. I was 56 when I was first diagnosed and am 61 now. I opted for feeling better most of the time vs. the drugs, but why not try them, see how you feel on them and take it from there. I tried 2 different ones and the Letrozole was better than the Arimidex for me. Everyone is different. I wish I could have tolerated them because perhaps it would have stopped my cancer from advancing to a Stage 1 ultimately. If they make you feel bad you can always quit them. If they are tolerable….perhaps you won't have the cancer again???? There are so many tough decisions to make at a time when you are least emotionally able to make them, so hugs to you.
