We experienced a case of advanced bilateral breast cancer during pregnancy. A 38-year-old woman complained of a breast lump in her right breast. She had noticed the lump two months before. She was pregnant at 5-months gestation. Ultrasonography revealed a huge tumor in her right breast, and also revealed swelling of the right side axillary lymph nodes. Furthermore, ultrasonography showed a low echoic mass, 10 mm in diameter, on her left breast. We performed core needle biopsies of these tumors. Both breast tumors were diagnosed as invasive ductal carcinomas. After waiting for the patient to give birth, we administered 25 cycles of TC chemotherapy (Docetaxel: 75 mg/m2/tri-weekly, Cyclophosphamide: 600 mg/m2/tri-weekly). After chemotherapy, she underwent bilateral radical mastectomy. The pathological diagnoses from both sides of the breasts were complete responsiveness to chemotherapy. She continues to be well without recurrence.
