AbstractThe aim of this study was to analyse individual cases of lethal breast cancer and not to evaluate the screening programme. Women aged 40-74 years who were diagnosed with breast cancer in 1990-94 and died on or before 31 December 1998, during the gradual introduction of organised mammography service screening in north Sweden, were included in the study. Out of 342 breast cancer deaths, 280 (82%) were in symptomatic patients whose cancers were clinically detected. Most breast cancers that proved fatal were already in an advanced stage and/or of high histological grade at the time of detection. A shift towards a lower stage was seen among screen-detected and interval-detected fatal cases. In a few of the cases with fatal outcome, in patients primarily presenting with histological grade I tumours of various sizes or small screen-detected tumours less than 10mm in size, early diagnosis by mammography followed by state-of-the-art treatment did not seem to have been enough to prevent death.
