Well, there seems to be a real consensus that I should push for a colonoscopy. At this point, my husband is willing to pay for it just to give me piece of mind. Appointment with the GI is this Friday. Hopefully I don't have to wait too long to get a colonoscopy. By the way, I do wonder if I would be really sick and have more symptoms if I had gone two years with undiagnosed, untreated colon cancer.
