After commencement of the screening programme there was a shift from advanced to early stages and at the same time the five year survival rate doubled. The mortality rates among the unscreened population remained high compared with the screened population. After 1979 the incidence rose again and reached a local maximum in 1984 but has decreased since then. About one third of the female population has not attended the screening at the recommended maximum three year intervals and two thirds of the cervical cancer was found among these since 1980. During the latter years there has been a shift in the occurrence of invasive cervical cancer from the older to the younger age groups. At the same time, up to 1985, there was a significant rise in the rate of preinvasive stages among women under 45 years of age. After analyzing the screening history, stage and histology distribution, we find that screening appeared still to be an effective approach to control most of the squamous cell carcinomas of stage I B and higher, but not the adeno- and adenosquamous carcinomas. Technical details such as strict working rules, central steering and an effective data-handling system are a prerequisite for optimal results in a cancer screening program.
