I had 33 radiation treatments. Things went well until exactly halfway through, We had even gone out to have dinner to celebrate how well it was going. And then, the next day, not so much. They actually sent me home a couple of times because of the burns. I started May 5 and ended on July 18 (2022). I don't know if I had fatigue from that or from the fact that I was also taking Anastrozole at the time (even though, normally, I have read, oncologists don't prescribe the pills until the radiation is over.) Of course, normally, oncologists order an oncotype (mine didn't and wouldn't even discuss it) and putting me on Anastrozole on Feb. 1, 2022, following my 1/27/2022 surgery less than a week prior, at a time when I was fighting a seroma and taking 500 mg. of Cephalexan every 4 hours for weeks was also questionable. And then there was the matter of ordering a bone scan BEFORE you put the patient on Anastrozole. I didn't get my bone scan until late May, either, and, as a result, I now officially have osteoporosis, whereas, going in, it was osteopaenia. My opening score was -1.4T and now it is pushing the -2.5T osteoporosis border. Radiation was much much easier than Anastrozole was. Tamoxifen was easier to tolerate than Anastrozole, but not by much. I'm pinning my hopes on the 33 radiation sessions (right side) I had.
