It is not scary to have breast cancer, and currently with the implementation of comprehensive treatment of breast cancer by medical development, breast cancer is one of the solid malignant tumors with better healing. The prognosis of breast cancer is related to the patient’s age, pathological stage, lymph node metastasis of the tumor, tumor biological behavior and tumor gene expression. Nowadays, the 5-year survival of stage I patients can reach more than 90%, and 60%-70% of patients can be cured, while the 5-year survival of stage II patients can reach 70%-81%, and that of stage III patients can reach 40%-50%, and the survival of patients in advanced stages will be significantly reduced. Therefore, early diagnosis, early detection and early treatment should be realized for breast cancer patients. At this stage, surgery is still the main treatment method for breast cancer, which also includes adjuvant chemotherapy, endocrine therapy, radiotherapy and targeted drug therapy.
