I have heard of young people with colon cancer but it's highly unlikely. I had a cancerous polyp found at 27, I guess it was lucky I had issues with UC or I wouldn't have gotten checked out until 40 or 50 and who knows what the polyp would have done by then? I would get a colonoscopy, it will ease your nerves.
Red blood isn't as much a threat as black blood or black stool. Red means it is fresh. Black means it was higher up in your GI tract and is more of a threat.
Diagnosed with mild proctitis in March 2007: Treated with Canasa (as needed)

Back on Canasa every other night + Asacol (9/day) + Probiotics + Iron
