Russ - there are many different reactions and experiences involved with the Rad Tx. My son had a rough time of it but what helped him was following the experiences of others who were going through the same experience and knowing that they were surviving and that he could, too. There are many things you can do about whatever symptoms present themselves. Recently, I've been impressed with those that have tried the Manuka Honey for the sore mouth/throat. When my son was diagnosed the cancer team gave us percentages of survival with the radiation and left it up to my son to decide. He chose the radiation treatment and I'm so glad he did! He's cancer free now and enjoying life! You can, too!
