Scared of diagnosis

Had concerns with upper abdomen pain for about 2 months.  Visits to GP.  Both ultrasound and bloods were clear but because it stated that the test may not pick up small pancreatic lesions,  this raised alarm bells.  A relative recently died with PC and he had problems with his stomach.  Very anxious which I am sure isn't helping.  My stomach is bloated and I am off my food.  Booked a private MRI scan.  Think doctors are fed up with me
