He is in ICU, but is doing great! You can tell he is feeling good because he makes continual comments on TV shows as he watches them, and has a 'lilt' in his voice instead of a more monotone voice.
He appears to be more coordinated too. Just the way he moves to get comfortable in bed and the way he holds things is more fluid and coordinated. It is subtle, but was enough for his Mom to notice.
He gets an MRI tonight to see how much of the tumor is left behind.
