title: Difficulties and errors in diagnosis of breast neoplasms.
abstract: Many perceptual and interpretive factors influence the radiologic detection and assessment of breast neoplasms. Diagnostic problems can be divided into errors of detection and errors of assessment and management. Detection issues may relate to inherent features of the tumor or surrounding tissue, technical problems, or human error. Even when lesions are successfully detected, errors in assessment or management recommendations can cause diagnostic delays. Improper breast imaging-reporting and data system (BI-RADS) usage or failure to integrate mammographic, ultrasonography (US), and magnetic resonance imaging (MRI) findings with clinical findings, all lead to interpretive errors. This article reviews factors affecting the detection and diagnosis of breast cancer, to improve radiologic interpretation, benefit patients by earlier cancer detection, and lessen medicolegal exposure from a missed or delayed cancer diagnosis. Mammography is the primary imaging modality for population-based breast cancer screening, and it is also the usual initial examination performed for diagnostic evaluation of clinical or screen-detected breast abnormalities in women aged 40 years and older. Mammography is supplemented by breast US and/or breast MRI in some cases. This article will, therefore, focus on mammography in reviewing difficulties and errors in cancer diagnosis, with supplemental discussion of breast US and breast MRI.
