Radiation treatments symptoms and conditions

I was diagnosed with breast cancer in 2003, age 53. I had excellent medical care at NW Cancer Specialists, Dr. D. G., Portland, Oregon. I endured Chemo (8 treatments) I had a lumpectomy and 36 radiation treatments. I also took Arimidex from 2004 - 2009. My doctor suggested exercise would lessen the side-effects and he was right. I followed everything my doctor told me to do, it was very difficult at times, but we are talking about my life and the quality of my days, his suggestions worked. I began a regime of walking, up to 3+ miles a day, water aerobics 3 times a week and I joined Curves. I also took vitamins: Costco multiple vitamin, vitamin E & C, Calcium + D(Viactive), Melatonin (natural sleep aid), probiotics, and fish oil. I also drank up to 6 glasses of water a day. I am now "cancer free" and not taking any RX.

I received radiation for breast cancer in 2001 and a month after the radiation treatments I was hospitilized with radiation penumonitis. I was given 120mg prednisone. I had horrible mood swings, kissing ulcers, and lost 15 pounds - the doctor's couldn't belive it. I lost muscle mass in my right leg and had to have physical therapy to be able to walk again. It took 6 months to work my way down to 2.5mg at which time I was hospitalized again with cryptogenic organizing pneumonia aka BOOP in my other lung. I was put back on 60mg prednisone. I have been on various drugs to combat the side effects. I finally got off prednisone in May 2005 but the end of June I got pneumonia and another inflamed lung. I went back on 10mg prednisone which I am trying to get off of now. I have been experiencing depression since going back on my latest dose, but am not currently medicated for it. I have returned to my normal weight and continue to do weight training to combat osteoporosis due to the prednisone as well as strengthen my leg. I worry about the long term effects of long term steroid use.
