Hi, Peary! I am glad you found us, but sorry it was under such difficult circumstances. Here is a link to the topic here of Stages of End-Stage Liver Disease:
It is listed on the same page as the thread you began. That should help you a lot. As to the tumors, if they are not cancerous then that is a relief. I had a huge cancerous tumor of the rt. lobe of my liver, but it was treated and the rt. lobe removed, and I am fine now. If your dad drinks alcohol, he needs to stop immediately, as that is the worst thing one can do to the liver. Other than that, make sure he gets plenty of fruits and vegetables and stays hydrated with water. Green tea is also good. It's best to stay away from meat, as that's the hardest thing for the liver to break down. A little fish or poultry a couple of times a week is okay. Other than that, just wait to see what the doctors recommend.
I hope you will post again and let us know what treatment, if any, was decided upon.
