[Risk group oriented early detection of cervical cancer? (author's transl)].

In a retrospective case-control-study 500 women with a carcinoma in situ of the cervix uteri and 500 controls were examined by a standardized interview and compared by matched pair analysis. 8 risk factors for ca in situ were found indicating a lower social status, earlier sexual activities and more frequent inflammations of the cervix uteri. However screening programs should not be restricted to such women because it is difficult and expensive to identify and to reach the high risk group.
