Hi Kent
I had my tumor removed from the right side of my tongue. Initially the doctors were telling me that at least 50% of my tongue was to be removed and quite possibly a neck dissection to boot. It ended up not being the case, but it just goes to show you never know. My tumor was shrunk significantly by induction chemo which helped my case tremendously.
For me, the chemo and the surgery were a breeze compared to the radiation that followed.
What part of your tongue is your tumor located?
To get ready, I will echo what has already been said, eat like there is no tomorrow as much calories and protein as you can stand. The weight loss is usually quite dramatic.
Keep a good attitude, it will help more than you can possibly know, and by all means ask questions both of your doctors and here.
