And on top of all that, HPV-16 is now preventable with the anti-HPV vaccines. (We don't yet know for certain that the vaccines prevent oral HPV
-related oral cancer
, but probably they do.)
Can I guarantee that you don't already have, or that you might not catch, HPV-16, either orally or genitally, or that you might not get oral cancer from it someday? No, but the risk is very low. I also cannot guarantee you won't be killed by lightning, a meteorite, or in a commercial plane crash.
