Runner 1256,
Welcome. I am glad you caught this early. I am sure your research has shown squamous cell carcinoma is nothing to take lightly (all cancers are serious obviously). I had to re-read about this special type see:

You have done everything right by getting a second opinion to confirm and get an attack plan. The last piece is simply keep and make those follow ups. If memory serves me this is Mott in the Tampa area? Seems they have a good reputation.
