Where the radiation is mapped or directed is very important in how one's organs respond which is one reason why some experience life altering side effects and others have none. [/quote]

Thanks, davidcpa, for your kind words. My reasoning is because the cancer didn't have clear margins, the doctors couldn't protect some of the areas which are vital in John's maintaining his swallowing functions. They just had to fry everything. Yesterday the doctor said that John was one of those who were sensitive to the radiation and the sensitivity caused much scarring in the areas treated. The positive side of this is the Tx probably worked better with the cancer, the flip side is that the scarring is causing the swallowing difficulties. I guess one has to take the good with the bad.
