I found the radiation therapists at my centre the best people of my whole experience, which for me was a 2 edged sword. I developed good relationships with them through my 6 weeks.
The nurses, however, were another story, which saddened me, as I am a nurse.
The radiation therapists were the ones who listened and helped with any issues. The nurses generally told me everything looked fine.... even when I had a raging mastitis 2 weeks in.
The vacbags sound interesting. Don't know if they're used where I am. They certainly weren't 2 years ago when I was treated
