my husband had SCC 4 and then a new occurrence nearby this last year. He was being seen at University of Iowa but they said it was inoperable. He went to Mayo clinic a few days later and they offered proton therapy. Just saying there are option out there and if you feel things are progressing, do not be afraid to get a second opinion from Mayo. It can't be that far away if you are currently going to University of iow.

He's 7 months out from treatment now and has gotten clean scans twice.

Best wishes.
