I am going to extend Dr. Holohan's time. I have a question on that. In a case of a false negative, and the frequency of testing is every three years, the rate of growth of cervical cancer is slow. If someone has a false negative and she comes back in three years' time, is there an estimation of how advanced that cancer would have progressed in those three years? The benefit of screening is that women are screened every three years in order that a profile of the patient is being built up. If there is a false negative on one smear, how much of a change would be expected in a three-year period?
