Breast cancer anticancer drugs refer to the drugs that can treat breast cancer, which are mainly categorized into chemotherapeutic drugs, endocrine drugs and targeted drugs. Chemotherapeutic drug treatment is one of the main means of treating breast cancer at present. Breast cancer chemotherapeutic drugs include anthracyclines, such as epirubicin and doxorubicin; paclitaxel, such as docetaxel and paclitaxel; and platinum drugs, such as carboplatin and cisplatin. These drugs generally interfere with the reproduction of cancer cells by altering or inhibiting their biochemical metabolic processes. Endocrine therapy is a treatment for patients with estrogen receptor-positive breast cancer. Endocrine therapy drugs are estrogen receptor antagonists or estrogen receptor downregulators, and aromatase inhibitors used in postmenopausal women. Common endocrine drugs include tamoxifen, toremifene, anastrozole, and exemestane. Targeted therapy for breast cancer refers to the use of drugs that specifically bind to the HER2 protein on the surface of tumor cells, thus pinpointing and attacking the tumor cells to treat breast cancer. Common targeted drugs include Trastuzumab and Patuzumab. If breast cancer is detected, it is recommended to go to the hospital to receive standardized treatment, do not blindly use drugs.
