Re: What is the science behind Pap Smear screening guidelines?

I just checked a medical website and this is where you're getting the 70% figure:
"Virtually all cervical cancers are caused by HPV infections, with just two HPV types, 16 and 18, responsible for about 70 percent of all cases (5, 6). HPV also causes anal cancer, with about 85 percent of all cases caused by HPV-16. HPV types 16 and 18 have also been found to cause close to half of vaginal, vulvar, and penile cancers (7).
Most recently, HPV infections have been found to cause cancer of the oropharynx, which is the middle part of the throat including the soft palate, the base of the tongue, and the tonsils. In the United States, more than half of the cancers diagnosed in the oropharynx are linked to HPV-16 (8)"

So 2 high risk strains of HPV (16 and 18) account for 70% of cervical cancer cases and the rest are caused by other strains of HPV.
Thus HPV negative and not at risk and that's why these women will not be offered pap tests under the new Dutch program. Hope this helps..
