Patient: Hi Dr. Hui: My mother was diagnosed with breast cancer in February 2008 and underwent radical left breast surgery. The pathology report is: invasive ductal carcinoma of the left breast, 3.5 cm in diameter, and an adjacent medullary carcinoma, 2.0 cm in diameter. The drugs used were cyclophosphamide, epirubicin, and docetaxel. What other treatments are needed? Thank you very much ！！！！ Huirui, Department of Breast Oncology, Tianjin Cancer Hospital Huirui, Department of Breast Oncology, Tianjin Cancer Hospital: If the gland between two tumors (intertumor gland) is positive (malignant tumor cells can be seen), then it can be considered as one tumor. The question of radiotherapy depends on how the radiologist determines, the patient’s current state is between two possibilities, i.e. can be put or not. The chemotherapy regimen is okay, but I don’t know how the dose is. The patient’s current state is between two possibilities, i.e. radiotherapy or non-radiotherapy. If the patient’s immunity is poor, you can do immunotherapy.
