Advanced prostrate cancer spread to brain, spine and liver/what is life expectancy time?

Not long...: ...I'm afraid, particularly if it's spread to the brain. It may vary depending on whether he gets treatment and how well it works but in general his prognosis is very poor. I would focus on helping him feel as good as possible for whatever time he is given rather than guessing how long he actually has.

Not Long: Unfortunately in this situation even with good standard therapy life expectancy is less than a year in most cases.
