I'm a newbie to all of this - both the cancer and the online chatting. I feel I am verrry lucky - early detection - Grade 2 invasive lobular tumour. Tumour removed with good margins and 2 lymph nodes - no travelling. I am almost finished radiation and going well. So I'm about to start on the Arimidex. I am 59 and already have thin bones. I don't like the sound of all the side affects. Does anyone have stats on not taking the drug? Love to hear from anyone.
