Tests tomorrow scared stiff

Hi to all, just trying to get ahead of results of an endoscopy and colonoscopy tomorrow.  I was found to be anaemic and am being seen within 1 week.  I have an hiatus hernia and IB S for years.  Also had about 10 months to a year on NSAIDS, in last year and a few years intermittently from 2004 to 2010.  I have repeated bouts of abdominal pain, bloating, and irregular bowels habits but can see no blood.  Had my gall bladder out a year and a half ago.  Stomach pain for last two weeks has been almost constant.  I have lost about 4lb in last two weeks otherwise struggle to get it off.  Am terrified they are going to find stomach cancer.  Any thoughts
