The first time I had breast cancer, back in 2007, I did radiation treatments for 35 days. I have noticed that many people on this site say they have or are doing 30+ days of radiation. This past summer I did radiation again, but only for 21 days. Now I am wondering why mine was so short. I ended up leaving my oncologist this time. He did things that aggravated me…like having his own agenda and not wanting to listen to me or answer my questions. It bothers me that he never suggested proton therapy instead of radiation…I would have liked to have known if it was an option. I feel that I should have been made aware of it. I am interested in knowing if many of you have had the accelerated radiation treatment like I did.
