Killer diseases and body malfunctions have a range of life expectancy. I'm guessing the February date used the average. McCain is gettng top shelf care too, which tends to shift the "curve" to longer life.
How long does someone suffering from glioblastoma typically survive? About 16 months on average.
And this too ...
For adults with more aggressive glioblastoma, treated with concurrent temozolamide and radiation therapy, median survival is about 14.6 months and two-year survival is 30%. However, a 2009 study reported that almost 10% of patients with glioblastoma may live five years or longer.
Thanks for the “good” news ; )
