There's been a virus found in some cancers. It has not been found in others. We could look at people having oral sex with cold viruses and cancer and form a link if we wanted. There's a positive correlation between organic food sales and diagnoses of autism, doesn't mean organic food causes autism.

There has, to my knowledge, been no study where an animal has been infected then the cervix studied and biopsied for cancer. So no proof of cause. Just a link, a positive correlation, a graph. Not proof.

And I am interested in a study about sexual risk not for promiscuity or judgement or anything like that, just curious how it or if it changes behaviour in a large cohort. But then that is very much going back to my research roots.
