The results from the prevalence round of a population-based mammography screening program in Uppsala county are presented. We invited 48 517 women aged 40 to 74 years to mammography screening. The age subgroup 40 to 54 years was examined with two-view mammograms, while women in age group 55 to 74 years were offered one-view screening. The number of attending women was 41 761 (86% of those invited), of whom 2002 (4.8%) were recalled for further examinations, and 423 (1.0%) were referred for surgical biopsy. A total of 241 (0.58%) women were diagnosed to have breast cancer. About 1/3 of the cancers were stage 2 or more advanced, but only 20% of the invasive cancers had lymph node metastasis. The median size of an invasive cancer was 16 mm. After age-adjusting the cancer rate, the results indicate that the Swedish two-county study can be duplicated in clinical practice.

To evaluate, by analysis of breast cancer mortality data from all the 26 Swedish counties for the years 1971 to 1990, whether the effect of the introduction of mammography screening in Sweden can be assessed by observation from existing mortality data. A Poisson regression model was used to study whether a decrease in breast cancer mortality among women aged 50–74 years was associated with the extent of mammography screening in different counties and periods. In regions where mammography screening had been introduced, breast cancer mortality tended to be decreased, on average, compared with regions with-'out screening. If a 10 year time lag between the start of screening and its full effect on mortality is assumed then the estimated reduction in breast cancer mortality associated with introduction of screening was 19% with a 95% confidence interval ranging from 3% to 37%. The results suggest that the effect of mammography screening may be studied using existing routine mortality data and appropriate statistical modelling. This way of assessing the outcome of the screening is valuable when continuously monitoring a screening programme that has become a public health routine.
