I knock down a few beers. I did do the pouches when I fished. But, I broke a tooth and cut a sore into my tongue. It was infected before the dentist could get me in. He fixed the tooth, but sore never healed.
Cells in the mouth are fast growing and something mutated one. Was it the beer, tobacco, coffee, x ray from dentist,, cell phone stuck to my head all time, ultra processed foods, radiation from all the monitors I look at, sunspots, etc. My Oncologist just said pure dumb luck, when I asked him the cause. And I ride with that, never will know the actual cause.
I have moved cell phones away from my head since whenever possible. Head and Neck cancers are growing in numbers and I really think they are a possible factor. We have had all the other factors for a long time. But who is ever going to regulate those in this cell phone society?
