Hi all,well, here is my situation - over the past - well, I don't know how long, but at least several months, and more likely couple of years, I have had some gastro symptoms. Less regularity, and occasional flattened or very thin stools. These symptoms usually are accompanied by stomach discomfort, and are particularly acute after a period of constipation. I will also often have a period where I have "normal" stools, followed by these thin ones. I have always had a sensitive stomach, and had an ulcer as a kid. I am now very worried that I have colon cancer - a web search for "think stools" pretty much only brings up obstruction, and >50% of obstructions are apparently tumors. Add to that the fact that most sites about colon cancer say that by the time you have symptoms, it is "advanced" - well, I am a mess right now.I KNOW I need to see a gastro - in fact, I have an appt this week, but I was just hoping for some insight from folks here.Thanks,Fishedit - I should add that I specifically am hoping for info about if this sounds like it even COULD be IBS?
