Rosemary,

As I have mentioned before I now have mets to the liver and bones...when they did radiation they only did one side. My doctor (ENT)told me when I asked why I wouldn't get it on the other side, quote: "that just doesn't happen". Neither he nor the radiation oncologist even mentioned doing both sides.
My excuse at the time is that things were happening so fast - we put our trust in these docs.
Does it have anything to do with now a year later ? I don't know. And I'm not in the medical community as a profession, but I can tell you if I had it to do over. I would have insisted...Rosemary I've been on this board only since July...but Brian hasn't been wrong yet and he's who lead me to a doctor for my liver.
Good luck and I'm sure you can convince your daughter dry mouth is not the priority here. Living is.
Take care,
Dinah
