ill pray for him, im totally know what your going through, last june my father was diagnosed with brain cancer and he too had a pretty low chance for survival, but here we are in march, and hes still kickin it, fightin away, we even got him skiing this winter after being paralized on the left side for about a month, the new medicine's and technology that the medical industry has come out with are amazing, and im sure your father will fight it fine.
