Breast cancer (BC) is the second leading cause of cancer-related death in women, with mortality primarily associated with metastasis. Although gastric metastasis is rare, there are still case reports in the literature. Clinical symptoms of gastric metastasis from BC are often nonspecific, and endoscopic presentations are heterogeneous. Distinguishing between primary and metastatic tumors is important and challenging for the endoscopist. Herein, we report a case of gastric metastasis occurring 4 years after BC surgery. The timeline is as follows. In 2019, the The patient remains alive under maintenance therapy. In summary, our case highlights the role of ESD, which was performed with both diagnostic and therapeutic intent-in managing gastric metastasis from BC, while underscoring the necessity of regular endoscopic surveillance post-mastectomy.
