I'm surprised your doctor didn't get into detail about radiotherapy - usually they are very up front about it - even my surgical oncologist warned me!!! He pretty much said you did really well with surgery - radiation won't be anywhere near as easy - then I researched and asked questions and attended meetings about it! They were all offered by my hospital - I would say you have a right to be upset about being not told - but one thing I have learned through this journey - you have to advocate for yourself! Asking questions will not hurt!!! Now that you are done and recovering - let go of the anger- it serves no healthy purpose - focus on you and getting better!!! Sorry if I sound a little like yoda today - having a zen moment! Take care
