- Hi, I had some investigations done for abdominal bloating and incidentally I was found to have a large polyp in my gallbladder. I was advised to have my gallbladder removed which is happening late October. Since then I have had a CT scan which showed a focal smooth wall thickening which the significance of was uncertain. I have since had blood tests which show normal liver function but a raised CA19-9 of 144. I have another uss on Sunday but I have not heard from anyone. Do you think I should be preparing myself for a diagnosis of cancer? I have a MDT meeting at some point. Other history is I have type 1 diabetes
