Ok, here is a good one for you:

22 year old Mormon, never smoked or drank. Diagnosed with SCC and we guess it was due to the ozone and ash from his primary occupation and a welder?

This is one factor that I have in common with him as I spent years running a carbon arc image burner. I can't say that was the only risk factor that I had, chemical gasses ... but an interesting connection.

Or maybe it's just the luck of the draw??
