<s>[INST] Hello,I am 33 years of age and recently started having irritating aches in my upper abdomen.  I have seen my Dr and she initially did  a xray to see if it was related to constipation.  She had me take Prylosec and murilax for 2 weeks which really did nothing.  Now she would like me to do prylosec for another 6 weeks.  I am wondering what my chances are of this being something more serious such as gastric cancer or colon cancer as these are my greatest fears right now.  My medical insurance has a very large deductable so I am unable right now to just go get lots of expensive testing.I am not a smoker, I exercise and eat relateively well, I am not overweight and have no family history of cancer.  I do drink a little more then I should but nothing to excessive.Any info you give me would be much appreciated. [/INST] Hi. Thanks for your query and an elucidated history. Read and understood your problem. You are 33 years old and have irritating aches in upper abdomen and under Prilosec and MiraLax. Gastric Cancer and Colonic Cancer certainly can be diagnosed only by Endoscopy and colonoscopy and needs to be done irrespective of the Insurance cover or not. This is important as early diagnosis helps in better treatment and prognosis. Get one done ASAP. Another probable reason is an ulcer or cancer, Pancreas problems, duodenal conditions. Till then, I would advise you the following:A 5-day course of an antibiotic, metronidazole and probiotics with symptomatic treatment. </s>
