Now dad has pnuemonia so is being admitted to the hospital; I wonder if this is because his system is soo compromised by the radiation or the cancer or what.

My Dad - 85 yrs old; 9/09 diagnosed T3NOMO; rad/low dose chemo; all clear; 6/10 - L retomolar trigone; more chemo; seems to have shrunk; 10/2010 back - significant ulcerative mass in the left retromolar trigone extending into the left tonsil
