Outcomes of atypical (B3) core biopsy lesions diagnosed across BreastScreen NSW, Australia

CONCLUSIONS: The overall upgrade rate of B3 lesions to malignancy was 26.4%. The majority of the lesions were upgraded to DCIS instead of invasive cancer. Upgrade rates varied by lesion type. Lesions with atypia had significantly higher upgrade rates to cancer compared to lesions without atypia. Malignant lesions were significantly larger than benign lesions.PMID:38564975 | PMC:PMC10993176 | DOI:10.1016/j.breast.2024.103720
