HPV16 does not produce visible papillomas was a rule. That is the real problem with it, that it can develop inside the tonsil, and other non surface, not visible places and become well established before any discovery of it as a cancer could take place. There are many versions of HPV that do cause the growth of papillomas of different shapes but most often a small cauliflower looking growth that is easy to see. Those are not cancer causing types. (usually version 6 and 11) Papillomas are by and large benign, and while they can cause irritation and if left uncontrolled grow to a larger mass, or in extreme but rare cases cover large areas, becoming a problem, they are not cancer causing. There are some really rare problems that occur with papillomas that I will not scare you with, (I've only seen them over the years in medical journals, never in a real person) but they are like I said rare and they are not cancer.
