Long story short, I have been having blood in my stool as well as pain under my right rib cage, bloating and back pain. I had a CT scan and colonoscopy, which both came back normal, except for tiny luncencies in my liver, too small to characterize, likely representing cysts. My doctor said anything this small wouldn't cause pain. I just recently had an ultrasound which showed everythign, including liver, was clear. My liver and CEA were all normal too. How accurate are colonscopies and ultrasounds at detecitng tumors? and how often is liver enzymes and CEA elevated in symptomatic liver cancer? Thanks!!!
