My father is liver cancer at the moment and his bilirubin level increasing almost 13. the doctors couldnt drain his liver. what can we do to dicrease?

May not be possible.: Liver cancer is obviously very bad. I'm sure I don't need to tell you that, given what you're going through with your father. The increasing bilirubin may just be related to compression of the ducts from the growing tumor, and there may really be no way to lower it. Unfortunately just another part of what he's unfortunately going through.
