Lésions frontières en pathologie mammaire à fort risque de surdiagnostic : lesquelles ? Double lecture anatomopathologique, une nécessité ?

Overdiagnosis is a side effect of mammography screening, it is inherent to the act of screening but is also due to overinterpretation of mammography images by radiologists and borderline lesions by pathologists. Borderline breast epithelial lesions are intraepithelial neoplasias with a morphological continuum, rendering categorization difficult and subject to diminished interobserver diagnostic reproducibility. The French national cancer institute has recently issued recommendations for the renewal of the national breast cancer screening program, including improvement of quality in pathological diagnoses, through experimentation of pathological review of breast borderline lesions.
