I was afraid you would get that diagnosis. Yes, incurable is another term for terminal. However... chemo can be used to extend her life. But the time will come when you will need to weigh quality of life over quantity.
I would definitely seek out a second opinion right away. Of course its your choice but I feel CTCoA is not a good option. CTCoA honestly does not have the best reputation, it isnt a CCC even if it leads people to believe it is. I would doubt they would be of help, they patient shop so their numbers appear to be better than other centers.
