Hi,
I assume that you got the diagnosis of leukoplakia from your biopsy but, I too don't know what you mean by 99% chance of CX.
I hope that you have stopped using the chewing tobacco. Even without a diagnosis of cancer this will be a good opportunity for you to stop. I have seen patients with cancer from dipping and you don't want to go there.
As Leslie said, you can learn a lot by reading posts by outdoortexan and visiting his site at
