question: My 75 y.o. father has been diagnosed with advanced gallbladder cancer which has metastasized to the liver. He has had biliary bypass sx to allow him to begin drinking and eating soft foods. Palliative care will be offered. We meet with an oncologist in a couple of weeks. Just curious what the life expectancy might be for someone in his situation. I realize every patient is different and not knowing the history, just what I have given here, am hoping to get a general idea. From research I'm learning less than 6 mos.
