Hi Don....
Wow, You will sure be able to give the docs a great history. Welcome to the group. I know its hard to imagine, but you will come to get a handle on this diagnosis and deal with it in your own way. Your mom is very lucky to have you on her team.
There are so many factors that play into what type of treatment we all receive. So many of us have had different combinations so it is hard to say which is in her future.
I wish you both the best.
