Warren, At first, you won't have a lot of visible changes from radiation. as time goes on you are likely to have some swelling and some radiation burn, although how bad this is varies for everyone.

As for preparing yourself for radiation, the main thing I would recommend is use the next two weeks to eat as much as you want of the stuff you love. If you put on a few pounds, rest assured that they are likely to come off, and probably more than you put on, during the radition treatment. And food will taste awful for a while starting one or two weeks into rad and some things may not ever taste completely right again (I think this may be especially true when you get rad to a cancer site on the tongue. I have a lot of my sense of taste back but it's not 100% and I think it probably never will be).

There are all sorts of other things you might want to stock up on for use during treatment but if you are having just radaoition, you have time before you'll start having any side effects. So for now, eat and enjoy!
