Is Mode of Presentation of B3 Breast Core Biopsies (Screen-Detected or Symptomatic) a Distinguishing Factor in the Final Histopathologic Result or Risk of Diagnosis of Malignancy?

Background The relation between histopathologic subclassification and mode of patient presentation (with a screen-detected vs. symptomatic lesion) with an abnormality in the breast core biopsy classified as having uncertain malignant potential (B3) has not been previously examined. We compared the histopathologic subclassification of these lesions and the frequency of malignancy in screen-detected and symptomatic patient groups.
