Hi. I'm 22 and for the past couple years, I have had what I though was irritable bowel syndrome. I'm not 100% sure, but I get diarrhea/constipation/flat or stringy stools/stomach pain frequently. I am thin and eat plenty throughout the day. I was talking to a friend about it and he mentioned the dreaded "C" word. He said about how colon cancer or a polyp can have the same symptoms. Now of course I'm terrified. I have never before had a colonoscopy done before, and due to bad health insurance, I want to avoid that. I'm in the process of a big move which is already expensive enough. Does anyone have IBS and can tell me if this sounds normal? Should I be concerned for Colon cancer? I'm terrified.
