My numbers were low too. Went on Anastrozole, I considered all my factors and I decided against radiation before I saw the radiologist. The radiologist suggested 5 days a week for 5 weeks. I told him I decided not to do radiation. He then looked at my records again and said that seemed like a reasonable choice. Had I not said no,they would not have given me the option and would have gone ahead with it. Do your research.
