Abstract
Between 5% and 10% of women have distant metastases when they receive a breast cancer (BC) diagnosis. Metastatic BC is associated with poor prognosis but advances in systemic treatments have improved survival rates in recent decades. Debates about local primary tumour management in metastatic stages continue, but multiple studies have shown that primary tumour surgery can be beneficial. BC is one of the most commonly diagnosed neoplasias during pregnancy. Treatment of pregnant BC patients should follow the standard treatment of young, non-pregnant patients as closely as possible. We present the case of a young, pregnant patient with metastatic BC with a complete clinical response to chemotherapy followed by surgical treatment.
