Welcome David
Sorry about your diagnosis, but be assured that in Melbourne you will receive excellent, and I'm sure effective, treatment.
I also had tonsil cancer diagnosed over Christmas 4 years ago and am happy to report that I'm now well although I do live with the after effects of the treatment as most of us do.
I had radiation to my throat and both sides of my neck. I got through it day by day and was able to take myself to each treatment. I didn't use a feeding tube, but did lose a lot of weight. I was too fatigued to work.
I wish you well, when you need support people here are very understanding and generous with their experiences and will offer all they can.
Email me if you wish, all the best to you and your family on your journey.
Helen
