Cazz, in my case I was initially scheduled for six weeks of radiation and then when I was nearly finished with the original dose, I was told that I needed six rounds more focusing on the left side of my neck only. There was no scanning during the treatment and my oncologist explained that the increased dose was essential as a further boost. At that time my neck was already severly burnt and bruised and I hesitated to have the extra dose. But my oncologist was firm and reassured me that I could stand it. So here I am without regret that I took my oncologist's suggestion finally. Your brother's doctor is right that the radiation takes some time to show its effect on the tumor.
