Since the documentation has been looked at in more depth, what I suspected...I must give you a bit of background.
Cholangiocarcinoma is a difficult diagnosis to make. It comes on very quickly. Frequently, the very first symptom and sign is that the patient presents jaundice, and they usually have a history of feeling tired. At that point, it's very often too late. So we rely on diagnostic imaging by CT, MRI, and ultrasound. Frequently the patients are too ill to be biopsied. So on the basis of the clinical picture, the picture built up by the tests we can do or manage to put together, and with experience—and, in the end, an educated guess, which is part of the art of medicine—my presumption at that point was that we were at least dealing with a biliary tract cancer, possibly into the pancreas. There was not a lot of pain, and painless progressive jaundice is something that can be a very distinct hallmark of this type of cancer. So my presumption at that point was that it was at least biliary tract cancer, if not cholangiocarcinoma.
