My radiation therapy starts tomorrow April 6. I've had a brain scan which showed there was no  Metastasization of the lung cancer, but they did discover a small brain tumour. After 3 chemotherapy treatments about the only thing I notice is that I'm a little light headed all the time and my voice has gone up a couple of notes. Other than that I feel pretty good. I have a tee time at 8 o'clock here in Alabama. I will let you know how I really feel after that.
