This is a study that I like to quote, in 833 cervical cancer patients, and this was published in the Journal of the National Cancer Institute, a very good journal, 32% of the patients that had cervical cancer were attributed to Pap test detection failure.  In other words, the woman did exactly what she was supposed to do and the system failed.  You can still get cervical cancer if you get your Pap test regularly.  That is why we have a better test, a molecular test, an HPV test.  So, here it says of particular interest are the failures and detections of patients who had multiple Pap tests.  So again, even if you get them done regularly, it is all about the adjuvant or adjunctive test of HPV.
