Of course most cervical cancers were caused by HPV forty years ago -- we did not know it, the tests were not available, etc. That's like saying that, until the early '90's, none of the cases of non-A, non-B hepatitis were Hepatitis C.
I've given a few radio interviews on the vaccine the last 2 days. Each show - and one of the threads here on FR - has received a personal story of a woman who contracted the virus within marriage and/or one who was the victim of rape. I've seen 5 or 6 women - girls, really, all under 25 - in my practice with high grade lesions who then disclose that they were victims of rape when they were in their early teens.
Here's a great review article on HPV:

Unfortunately, we're finding that some strains can cause the carcinoma in situ and even the cancer more rapidly than we thought.
"" . . . Winer et al followed women
after initial HPV infection for the development of CIN 2/3.
As shown in Figure 3, approximately 27% of women with an
initial HPV 16 or 18 infection progressed to CIN 2/3 within
36 months. A second study of a large health maintenance
cohort found that approximately 20% of women 30 years of
age or older who were initially infected with HPV
16 developed CIN 3 or cervical cancer within 120 months.
Women who had an initial HPV 18 infection had approximately
a 15% risk of developing CIN 3 or cervical cancer at
120 months.""
I didn't say none. I said that 'koilocytotic atypia', now called HPV, was not a common occurrence in the cells of the vaginal tract when dysplasia was diagnosed. No, I don't believe that HPV was the cause of most of the earlier cervical cancers. Dysplastic cells frequently did not have the halos characteristic of HPV. Many of the cancers years ago were of the Keratinizing Squamous type. As far as I know this hasn't been linked to HPV. And, yes, it used to take years for cancer to develop but now, with the aggressive nature of some of the HPV strains, it can progress to invasive within a year or so.
Five rapes in one practice? I'd call that very unusual and very sad. Were any of these date rapes? I suspect that that is what's going on here.
