Hi DW,
there's an article in the news section that talks about the additional risks of oral cancer that smokeless tobacco can pose.
From the article,
"The American Cancer Society says that smokeless tobacco users are 50 times more at risk for developing various cancers than those who don't use."
You can read the entire article at

Good luck with your biopsy results. - Sheldon
