These follow-up scans after the hell you have all gone through already can really add to your anxiety about re-occurrence. And I hate to add that it can take years before you are comfortable knowing that this cancer is probably not coming back. Best advice I had was to convince myself that the nightmare is over and time to get on with living. It doesn't work 100% but it does help. Odds are you are all fine and on the mend. However, I sure do understand the worry.
