Welcome Paul.
I am a tongue cancer survivor. As you can see in my signature I was stage 4 Base of Tongue and had a radical neck disection. Things are going to get rough for you over the next several weeks my friend but all of us are here to help you in any way we can. Everytine the going got really rough I would think about my wife and children and how hard they had worked in supporting me and caring for me. I would then think about this... if I give up, what will happen to them and you would be surprised how that in itself will keep you going on my friend.
If you need to please feel free to private message me here or you can email me if you would like to. My email address is in my profile.
All the best to you my friend,
Billy
