Hello Doctor,I am suffering from stomach pain for last 3 days, but before two three weeks back also same problem was there since 1 year I am suffering from this like twice in a month (approx) and i consulted many doctors they couldnt identify what is the problem, and when ever i consult doctors they had given somany syrups and tablets for gas trouble, and now i have a doubt that it is pancreas cancer, Doctor how can i confirm that?
