Early Stage Node-Negative Postmastectomy Radiotherapie—A Behandeling Conundrum

A previously healthy 36-year-old premenopausal woman with no known family history of breast cancer presented with palpable nodules in her left breast. Diagnostic mammogram and ultrasound demonstrated an 8 × 4 cm area of segmental pleomorphic calcifications with scattered masses in the left breast at 7 to 8 o’clock. A biopsy of the anterior and posterior left breast lesions showed an invasive ductal carcinoma. Intermediate nuclear grade estrogen and progesterone receptors stained positive (>90%), and human epidermal growth factor receptor 2 (HER2) was equivocal by fluorescence in situ hybridization.
