Yvonne,
Mine was also T1 SCC. I saw a top doc at Penn (excellent hospital in Philly) went for a 2nd opinion with the top doc at Sloan Kettering (same doc that treated Michael Douglas) and my doc that I actually see at Fox Chase and they all said the same thing. That the cancer should be treated surgially only with a partial glossectomy (4 actually) but it was only cancer once in 2007. All the others were a precaution because I had some white spots..it was always severe dyaplasia.
I think in order for you to feel at peace with your decision, you should at least go for a 2nd opinion. As you can see I had 3 from some very good doctors and that is why I can rest at night.
