The current treatment methods for breast cancer mainly include: surgery, radiation therapy, endocrine therapy, chemotherapy, molecular targeted therapy, Chinese herbal medicine and immunotherapy, etc. The comprehensive use of the existing treatment methods is fundamental to obtain good results. 1.Surgical treatment: For early stage breast cancer, it is a radical treatment, while for more advanced breast cancer, it is often used as a palliative treatment. Total mastectomy with axillary clearance and preservation of the pectoral muscle is considered as a contemporary standardized treatment for stage I patients and some stage II patients. 2.Radiotherapy: It is one of the main treatment methods for this disease and is a local treatment. Radiotherapy is applied to: (1) radical radiotherapy; (2) preoperative and postoperative adjuvant therapy; (3) palliative radiotherapy. 3.Endocrine therapy: Like surgery and chemotherapy, endocrine therapy occupies an important position in the comprehensive treatment of breast cancer. The development of endocrine treatment plan depends on the determination of hormone receptors in tumor tissues. There is a clear relationship between hormone receptor measurement and the efficacy of breast cancer: (1) The efficiency of endocrine therapy for those with positive ER or PR receptors is 50%-60%, while the efficiency for those with negative receptors is less than 10%; the efficiency for those with positive ER and PR receptors is more than 77%, and the positive level of receptors is positively correlated with the efficacy. (2) The receptor-negative cells are often poorly differentiated, and receptor-negative patients are prone to recurrence after surgery; regardless of lymph node metastasis receptor-negative patients have a worse prognosis than positive ones; positive patients with metastasis tend to have skin soft tissue or bone metastasis, while negative patients tend to have visceral metastasis. (3) Determination of hormone receptors is now used to develop postoperative adjuvant therapy. Endocrine therapy can be applied as postoperative adjuvant therapy in receptor-positive cases, especially in postmenopausal cases, while adjuvant chemotherapy is the mainstay in premenopausal or hormone receptor-negative cases. It is worth noting that most people think that endocrine therapy for breast cancer is slow to take effect, but a lot of practice shows that endocrine therapy is not slow to take effect, and sometimes its effect is even as fast as chemotherapy, and it can take effect within a few days. Chemotherapy: Chemotherapy has become an active treatment for all stages of breast cancer, which plays a great role in improving the cure rate and prolonging the survival time. In early stage cases, adjuvant chemotherapy is given after radical surgery to improve the cure rate; in late stage patients, chemotherapy combined with other treatments can also alleviate the disease and prolong the survival period. Breast cancer is more sensitive to chemotherapy. Both paclitaxel and anthracyclines have clear evidence of prolonging the survival of breast cancer. Biological therapy and molecular targeted therapy: Herceptin and TDM-1 biological therapy targeting HER-2 proto-oncogene and lapatinib, a tyrosine kinase inhibitor, have shown excellent efficacy in the treatment of advanced breast cancer, and biological therapy and molecular targeted therapy will have a broader prospect in the future treatment of breast cancer. 6.Chinese herbal medicine treatment: Chinese herbal medicine is a useful supplement in breast cancer treatment, which can slow down the tumor progression by regulating the body function and enhancing its own anti-cancer ability; in combination with chemotherapy and radiotherapy, it can reduce the toxic side effects and enhance the anti-cancer effect. 7.Immunotherapy: For many years, people have been exploring the application of immunological methods to treat breast cancer. From the theoretical point of view, immunotherapy is the most specific and only kills tumor cells without harming normal tissues, and the therapeutic effect is systemic, which is suitable for treating non-limited tumors. However, due to the existence of complex immune escape mechanism in tumor tissues, the effect of immunotherapy is not satisfactory yet.
