Okay, let me jump in and add to the chain of causality or coincidence (depending on which competing study you believe) to note that in the decade before DX, I was a major Listerine junkie - swishing it through my teeth after stimudenting - four times a day (meals and bedtime) as part of my oral hygiene drill.

So now I can tell people that my Cancer was "Holistic" - triggered by a confluence of second hand smoke (recent post), mouthwash, incense (old post and also in OCF data base), and the Summers of Love from 1969 to 1981.

Seriously while The mouthwash issue for moot for me, I am switching my son over to non alcohol mouthwash like Biotene. Even the chance that this is only a contributing factor is too much risk.
