a very young looking 72 - still work full time from home - have been having issues for many years and it was diagnosed as bad IBS - see oncologist @ Dana Farber every 6 months - lab work done in August - "Fine" just had endoscopy beginning Sept -waiting to hear, pathologist report posted 2 wks ago - looks like issues with stomach, "not cancer" still waiting for response from doctor to explain it all.
Good luck with everything you are dealing with. I just remain pro active and try to be as calm as I can be. So many other people are being told the same thing about their labs being fine but they still feel so poorly. This cancer is like a Ninja hiding in the reeds, just biding its time.

God bless.
