Rahel - I was a tongue chewer in my sleep for years(I now wear a mouth guard). I would wake up many mornings with my tongue numb from biting on it. And guess what, SCC on the left side of my tongue. My Dr's do not committ that the SCC was caused by the chewing, but say it is definitely a strong possibility given the fact that I am a non smoker and was not HPV.

DX 2/10/09; Stage 1 SCC side of tongue; Partial Gloss; PEG in 3/3/09; 3 Cisplatin; 35 IMRT; PEG out 7/17/09; Eating via mouth and walking 3 miles/day 4 wks after treatment end. 50 pound weight loss; Clear PET 09/09 and 09/10
