Sorry, saw this after I posted first. This is the EXACT same thing my mother has / had. She just went back to work, and is fine. The meds they have out right now for this cancer are very good at passing the blood / brain barrier and are VERY good at what they do. He has a fighting chance. PLEASE don't give up hope yet. I know how horribly, horribly scary this is. You cannot give up hope that he'll do well. He just may be ok. I know i've said this before, but if you or he wants any information, resource, or just a sounding board, me, and my mother, are here for you guys.
