Abstract
During the years 1958 to 1978, 3 607 women with invasive cervical carcinoma were reported to the Stockholm-Gotland Tumour Registry. A decreased incidence rate was found among women born 1910 to 1930 when comparing the 5-year cumulative incidence rate for the different birth cohorts at the same age. A reduced mortality was demonstrated in the same way. The impact of large-scale mass screening on the incidence and mortality of cervical carcinoma is discussed.
