I am 27 months post tx and just went for a follow up with my rad doc last week. He showed me the graph that displayed the exact places where the radiation zapped me, as well as the doses. Based on the location of the tumor (left tonsil), my left salivary glands are no longer functioning because they received direct hits and the highest doses. I asked him if my right salivary glands would ever get any better (more watery like they used to be, instead of thick and pasty like they are now). I told him that I keep reading that the glands can improve UP TO two years after rad tx. My doc said that the salivary glands could still improve even AFTER two years. That gave me hope again, because I thought this was as good as it was going to get. I'm still a little doubtful though. I've talked with some people that say their salivary glands have that nice watery feel again, and to others who say that their glands are barely functional or pasty. I guess it just depends on the location and dose of the radiation that each individual gets and on the location of the tumor/s.
