Any idea.

I posted this earlier and Ken didn't make a comment but since then I've tried to find if there is a similar increase of oral cancer in the States.
I see it has a lower figure than other countries but it is the increase/decrease over the years that will indicate any evidence that there is a link. Anybody know?

Any comment Ken? (open parachute)

I've just listened to Dr Kennedy's video again when reminded by Ken's Open Parachute  lack of response and out of curiosity I checked oral cancer statistics.

• Since the late-1970s, oral cancer incidence rates have increased by more than four-fifths (83%) in Great Britain.

Just a coincidence?
