Kennock, As noted in some of the above, swelling can come from lots of different things, not just cancer. I had my tonsils out and rad/chemo and radical neck dissection and have swelling and pain in the throat most all of the time. I think its just the "new normal" others have mentioned. Don't let this mess up your vacation. If there is something to worry about, the next checkup in a month will be soon enough. Enjoy! Will pray for you both.
