Cervical screening revisited.

Abstract

Some of the achievements of cervical screening in the reduction of morbidity and mortality in different countries are briefly reviewed, along with a consideration of some of the aspects of cervical cancer screening programs. The latter include the organization of the program (e.g., whether it is organized by the national health authorities), the protection afforded by routine screening, the assurance of quality in cervical sampling and in the screening program, the screening interval, the age groups to be screened, the compliance of women to present themselves for screening and of health care personnel to provide appropriate follow-up and/or treatment for the lesions diagnosed, the problem of false positives and its relation to overdiagnosis and overtreatment and, finally, the cost effectiveness. It is concluded that a centrally organized and well supervised cervical screening program, cautiously executed and with all involved parties closely cooperating, can be a cost-effective means of combatting cervical cancer.
