I heard from my oncologist. He was pretty neutral about the idea. While in theory it isn't a bad idea, it would require moving to Canada. Too much trouble for no ascertainable benefit. He didn't sound as if there were any major medical or therapeutic downside. It is worth keeping an eye on, though.
