The idea of publically funded health-care is a divisive issue for many. I can only tell you of my experience.
I could have chosen almost any hospital/doctor here for my procedure. The drawback would have been some time and I would probably have had to cover some, if not all, travel expenses. After a good deal of research on treatment options, I found a surgeon. So, I chose him and the hospital he provides services in. It was also close to where I live.
I looked into all options I could. I even looked into proton at Loma Linda. I probably would have had to sell my house to do it until I could convince appropriate authorities here to re-imburse, but I was probably not a good candidate even in my own mind (also, just a small biz owner with insignificant extended health coverage). I had fairly high content and # of hits. My biggest concern was how do I know they got all what I got? Post surgery pathology was the best bet to answer that question for me, and that's why I chose surgery. Unless I'm wrong, I doubt the best imaging in the world would have found the unifocal, EPE I had on post-op pathology.
It ended up that after looking just about everywhere, I chose treatment that was close to home and covered by my tax dollars. So far, I've done well.
