....a nasty sexually transmitted disease that causes cancer with 95% certainty....

I hope you just worded this badly and that you really don't think that cervical cancer is a 95% certainty among those with HPV.

Wonder if Perry et al think that too? Could explain a lot.

Sorry, I did word that badly. Cervical cancer is caused 95% of the time by HPV, but it's not the case that 95% of people infected with HPV actually get cervical cancer.
