Hi Sophie,
I too am newly diagnosed with SCC of right lateral tongue, 2 cm, just had my bilateral node dissection 8 days ago and seem to be recovering well. It certainly is a doable option in my opinion. I would encourage you to get more opinions also as in my research I have found there are no set protocols with this fairly rare cancer. I had 3 or 4 opinions and they were all at least slightly different. Then you can go with the one that fits best in your situation and that you are most comfortable with. Everybody has different fears and expectations so the answer might be different for different people.
Good Luck!
Lucinda
