Hi, I have been treated with chemo and radiation and now on anastrozole for stage 3 breast cancer. Tests so far show no signs of the cancer right now. Been on anastozole for about 2 years and effects have become unbearable. Doctor said, LAST MONTH, don t stop taking it and I will be taking it the rest of my life. I said okay but was crushed. I stopped taking it 7 days ago and didn t tell doctor but feel great . SKIN COLOR came back, no shortness of breath, no longer bedridden for 95percent of time. Feeling normal. Mental function normal again and not depressed and glucose level improving(GLUCOSE LEVELS were )./reaching almost 300 Should I tell doctor and risk losing him as my oncologist? Will stopping increase cancer coming back? I know it is a risky cancer. I had began to feel like the pills were killing me. I am already diabetic, high blood pressure, and have multiple sclerosis. Pills have blurred my vision. please help me. I am a retired teacher. I am desperate on what to do. I once had a life.
