It's your choice totally, but since you asked I would opt for the radiation. You found this site so you won't be alone. So many of us have gone through exactly what you are going through.

Radiation/chemo is no walk in the park, but you can get through it. Since I have been in your shoes, so to speak. I'll tels you what my doctor told me at MDACC. He said If I were a 40 year old woman who got oral cancer with no risk factors I'd be doing everything possible to prevent a local reoccurance. He said if you don't get it all, oral cancer has the tendency to keep coming back locally and you may never get rid of it.

I think a second opinion is also a good idea.
