Mines was also squamous cell. My margins came back clear and my nodes were negative for cancer on the pathology.

My oncologist said because the recurrence rate is so high (30-40%), and there was some peri-neural invasion, and the tumour was relatively deep, I should still give consideration to radiation (although not chemo) as a preventative measure, but it was my choice.

He indicated there was no "wrong" answer, and it really is dependant on everyone's individual circumstances. I have decided to hold off on radiation for the moment, and keep a very close on eye on everything.
