Hello, my father recently was diagnosed with bilirubin and had a procedure done with a camera examining the a blocked bile duct by a mass. The doctor was not able to pin point if the mass and will be sent to have a similar procedure done again. I have read that with my father s symptoms and the mass that it could possibly be bile duct cancer the is usually rare. I would like to know what we should expect of the outcome. After having the camera inserted my father has felt very weak to the point where he needs assistance to stand up. My father is a very athletic man and had took a turn for the worse. Thank you for your time! Pat
