Terrib,
I also was diagnosed with SCC of vocal cord with NO risks either, HPV-, they could only come up with reflux being the cause? Wonder if your husband had an issue with reflux. Don't want to hijack the thread but really curious if he did. Mine was Stage T1N0M0 for which I'm thankful, will be going on 2 years, so holding my breath as we all do! Sorry for the intrusion!
