Keep praying. My brother (59) had seizures Oct 2005 and was diagnosed in December with stage 3 astrocytoma. He had surgery to remove the part of the tumor that they were able to remove. He had chemo-radiation for 35 days and now is on chemo (temodur) on a 5 day on 28 off cycle.
He's doing well and we're blessed to have him. No one thought he'd still be with us.
He knows as do we, that it is the power of prayer that has sustained all of us.
Will remember your nephew.
