Early diagnosis is not generally possible. People at high risk, such as women or Native Americans with gallstones, are evaluated closely. Transabdominal ultrasound, CT scan, endoscopic ultrasound, MRI, and MR cholangio-pancreatography (MRCP) can be used for diagnosis. A large number of<unk> s are found incidentally in patients being evaluated for cholelithiasis, or gallstone formation, which is far more common. A biopsy is the only certain way to tell whether or not the tumorous growth is malignant.
