posing a question need some guidance and thoughts

That's a tough call, Greg. I'd do it myself, but I've been known to make very poor public broadcasts if you know what I mean.

And, In all seriousness and not trying to be a downer...but if the cancer has spread to her brain, how much longer does she have before dementia rears it's ugly head?

I had a very good friend of mine have to go through this same thing with his Mom when we were teens, and the cancer really had an effect on her personality as soon as it went to her brain.

Just something to think about.
