Breast cancer screening in Sweden . The single modality approach . Four population-based breast cancer screening projects are in progress in Sweden , three of which are randomized studies . Mammography is the only screening method . 51 % of all carcinomas detected at the first screening were either in situ or invasive with a diameter of 10 mm or less . Axillary metastases were found in 16 % of the patients . Sensitivity was over 90 % in all projects . The ultimate aim of the randomized projects is to demonstrate the effect of screening on breast cancer mortality . It is estimated that mortality statistics will reach significant levels in 1983. ,
