My brother has glioblastoma. It was stage 4 when diagnosed on Dec. 17, 2012. Had surgery next day and all treatments available to him. Had one seizure in Nov.2013. In Feb of this year he had 2 bad seizures. Left him in a coma like state. Doctor sent him home to die. Said may have 2 weeks. Didn t put him on feeding tube for almost 2 weeks. They finally did because he started opening his eyes. Sometimes staying awake for several hours. No communication and body is totally limp. It has been almost 6 weeks now. I can t really say he really knows we are there. Seems to stare right through me. I know the Lord and feeding tube is keeping him here. My question is how long will his body hold on with the feeding tube, when I know the brain cancer is sure to still be growing.
