Annual mammography was performed in 51 per cent; these patients were a mean of 5 years younger at diagnosis. Patients who had annual or biennial mammography had comparable rates of impalpable contralateral breast cancer, 30 and 27 per cent respectively. The tumours were of favourable stages in 60 and 58 per cent respectively. Five-year disease-free survival following diagnosis of contralateral breast cancer was 75 per cent in both groups. When the contralateral lesion was detected by mammography, disease-free survival was better, irrespective of the stage of the ipsilateral breast cancer.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>No difference was found between the two groups in stage distribution and disease-free survival after the diagnosis of contralateral breast cancer.
