I had 4 sessions of radiation, but not with GK. It was a linear accelerator machine called the Trilogy made by the Varian company. It's supposed to have a very precise targeting capability.
I chose this treatment in hopes of preserving my hearing, as the Doctor I trusted the most was convinced it was the best choice. However, during my research it seemed the statistics are the same for any of the methods of radiation, so it really did become a personal choice.
I made the decision mostly based on the fact that I personally knew someone who had the same size tumor (1cm) and was the same age when treated, (55) and they're fine - never missed work, travelled a lot. So I went to the same Doctor and had the same procedure.
It's been almost 3 months and I'm ok so far. Still have great hearing, sometimes it seems amplified. It was hard to be in a room with a lot of people talking, but that's getting better. Can enjoy movies and live music again. I was really tired for the first month, but am getting my normal energy level back now. I still have issues with balance and dizziness, but I knew that might get worse before better, so am trying to be patient.
So far I'm glad I made this choice, especially when I hear the birds singing in the morning!
