Hi Blackcat1, I know how overwhelmed you feel right now. I had my lumpectomy Feb 6th and 1 week of radiation in March. I started anastrazole 3 weeks ago. the radiation made me quite tired for a few weeks and my breast felt a bit uncomfortable for a few weeks also- a bit swollen and pink. I still get some random shooting pains in my breast but nothing too bad. My skin was fine- a couple of tiny red bumps for about a week and slight itch but thats all. I used StrataXRT (very expensive- bought online) gel twice a day for a month, starting day 1 of treatment. The aqueous cream supplied by the hospital may have worked just as well but I had already bought the StrataXRT. I felt really wiped out straight after each treatment and went home for a nap most days.
All these things happen with longer treatment times too so, from my experience, a 1 week treatment plan is well worth considering.
I wish you you all the best -take care.
