Breast cancer chemotherapy regimen. Thus, chemotherapy occupies a very important position in the treatment of breast cancer. The commonly used chemotherapy drugs in breast cancer treatment include alkylating agents, such as cyclophosphamide; antimetabolites like fluorouracil, methotrexate, gemcitabine, and capecitabine; anthracyclines, such as doxorubicin and others. In recent years, taxanes, particularly docetaxel, have been used more frequently. Other drugs include mitomycin and cisplatin, among others. However, the specific chemotherapy regimen for breast cancer should be assessed by a professional oncologist. The regimen should consider the pathological stage, pathological type, whether surgery was performed, whether the surgery completely removed the tumor, lymph node metastasis, and other factors to devise a suitable chemotherapy plan. Therefore, it is possible that each individual might have a regimen that is specifically suited to their situation, and not all regimens are suitable for everyone.
