On a more personal note... My sister had a brain tumor when she was 24. Lived with it for about 2 and a half years, it didn't become serious until she had her baby, which the pressure from having the kid caused stress on her body which caused the tumor to act up. Doctors gave her 2 weeks, she lived a year and 2 months. I defiantly hope that your father pulls thru with this, I know how hard it is.
