Not sure if you have the BRCA gene so do not quite know where to go with this, also not sure of the type of cancer and it's grading so can't offer too much info but in my situation I just wanted to smack that bitch out of the ground so I took everything they offerred.
Ask all the questions in your pack or what you can get form here and do some research.
Speak to your medical team and figure out where you need to go. you may not be able to have radiation again at a future date if you have it now so that needs to be taken into account but please ask those involved.
