Hi Barb,
Welcome to OCF. I'm happy that you found this site so early on in your journey, it will help you.
My cancer was also on my tongue, on the right side. I've had 4 partial glossectomies. I won't lie, they are painful. Eating is virtually impossible for the first week at least. But...you will get through it. Plus you have a wonderful attitude and outlook and that is more than half the battle. I'm happy that you already feel that way.
I would suggest at least going for a second opinion. Where in Colorado are you? I have an aunt who lives out there and she was a nurse at a cancer center here in PA. I'm sure she would have some good suggestions if you would like me to ask her, just let me know.
