Congratulations @GorgyS on finishing radiation🥳
That is a difficult decision, I haven't heard of the trial, all you can do is read the paperwork, speak to the experts and do what you think is best for you. Maybe start a new post to see if anyone else is participating.
I had my first Goserelin injection today, they gave me a patch to numb the area and other than a tiny scratch it was painless. I also had my zoledronic acid infusion, and so far no noticeable side effects, although I assume they may come with time. I start Letrozole next week.
