Bonnie,
My tumor was in my left tonsil. My was "well differentiated" though. As for your concerns about losing the salivary glands; I had IMRT radiation and they warned me that I could lose some glands on the left side. I finished rad treatments about three months ago and I was setting here eating salty chips when I start reading this thread. I do have some loss of saliva, but I can still get by.

IMRT can spare a lot of the good tissue so you may want your daughter to look into it.
