Dad has liver cancer - will he live?

Very sorry to hear: Can't answer, though. Depends on how much cancer there is, where it started at (started in the liver or spread to the liver from somewhere else), his general health, and other factors. Even then, we cannot be 100% sure of the outcome of any patient. Talk to his doc, who may be able to give you a better idea. Truly hope he does well.

Only God knows...: Cancer doctors can make educated guesses based on tumor types, sizes, whether it's spread, and other patient factors (what associated illnesses does your father have and how severe they are). The types of treatment given, the response, and so many factors beyond our control go into living with or dying from a cancer. One thing is sure: A positive attitude helps. Treasure each day, and hope!
