August,
I too was advised by my surgeon not to have radiation. I had a cervical node on my neck removed that was positive for SCC. The surgeon did a bunch of random biopsies in my mouth and removed my tonsils all of which came back negative. As much as I wanted to follow his advice because it was the easiest path for me I knew that the primary cancer must be found. So I continued to ask for tests until it was foind via PET scan. And yes I'm having radiation and chemo now.
