A 37-year-old female patient with ductal carcinoma in situ with invasive upgrade. The patient was referred to our hospital due to a screening-detected calcification in the right upper outer and upper central breast. The calcification was assessed as BI-RADS category 4B by the breast radiologist (A) and the AI-CAD score was 92% (B). A stereotactic biopsy was performed, confirming ductal carcinoma in situ. However, after nipple-sparing mastectomy, the final pathology revealed invasive ductal carcinoma. No metastatic lymph nodes were found on sentinel lymph node biopsy
