Sheldon,
When Heather was first diagnosed, the doc said there was no genetic factor involved. Later, however, he said that all family members should be diligent in being aware of any oral changes, that we were at a higher risk now. I remember thinking that maybe because Heather had no known risk factors and her cancer didn't react the way they expected, that they just really weren't sure why she got it and figured they should consider all angles, whether proven or not.

My dad also died of oral cancer, but he was a heavy smoker and drinker and also waited until his was an advanced stage 4 before seeking treatment. Since his had an obvious cause and hers had no known cause, they didn't think there was a genetic connection, but they couldn't really rule it out either.

I've never read anything about a genetic connection either. But I too wonder.
