What the risk of penile cancer from past hpv warts? i've heard conflicting information.i've also read it's almost nonexistent in circumcised men.true?

Yes/no: For one thing, the strains that produce warts are not associated with cancer, but you could have picked up non-wart cancer associated strains the same way Since circumcised men have the whole penis available for monitoring, recognition & treatment before any cancerous change would be easier. There is no 100% prevention with a circ, but it sure helps.
