Nelie,
"Moderately well differentiated" means that the cancer is pretty much contained in one area. That should make you should be a candidate for IMRT. Another clue on your chart is whether the cancer is "focally invasive", that is also an indicator that the cancer is contained. Like Kirk I had a right tonsil cancer and they radiated both sides as a precaution. I have made a pretty decent recovery from the treatment and other than not being able to sing as high as I used too, still sing lead vocals in a band. I even forget a water bottle from time to time but I always had one around before the cancer. It did take a little while to make a full recovery - over a year. But we are all different and you may not have as bad a side effects as I did.
