The vast majority of these, and the vast majority of those not yet infected who will acquire oral HPV
-16 in the future, will never get cancer
. Finally, many or most of those HPV
-16-related cancers each year typically occur in older persons who also have the other risk factors you mention, such as smoking or excessive alcohol intake. Non-smokers and social drinkers will be at even lower risk.
So my advice is that you not worry in the least about oral HPV or its long term health consequences.
