[en] To evaluate the interobserver variation in interpretation of the mammographic findings suggesting malignancy. Sixty-two mammograms of proven breast cancer were retrospectively analyzed by 5 radiologists based on the 15 findings that suggest malignancy. Using kappa value, the degree of interobserver agreement was calculated. There were fair to excellent interobserver agreements for 5 findings which were clustered microcalcifications(k=0.7642), ductal calcifications (k=0.5463), lobulated mass(k=0.4539), asymmetric breast parenchyma(k=0.4487) and nipple retraction(k=0.1572), duct ectasia(k=0.0200). The most reliable finding suggesting breast cancer was clustered microcalcifications
