You've heard it all. I'm going through the same thing. Basically, the bottom line is that the magic number for being considered a recurrence is .1, below which it's an uncertain thing. So though I still have concern, I manage it by staying active and thinking positively, because honestly there is nothing to be done other than wait an see.
The waiting can be nerve racking if that's all you focus on. So we have to accept it and keep moving forward...hard as it may be some days.
Good luck and hoping the best for you.
