Invasive breast cancer grade 3 triple-negative, can cooperate with doctors to receive comprehensive treatment such as surgery, chemotherapy and radiotherapy. 1. Surgery: After perfecting relevant preoperative examination and excluding contraindications, patients can consider receiving surgical treatment. Commonly used surgical treatments include breast-conserving surgery, simple mastectomy, radical mastectomy and so on. 2. Chemotherapy: If the size of the tumor is relatively large, chemotherapy can be given before surgery to reduce the size of the tumor, which is conducive to complete removal of the tumor. Receiving chemotherapy after surgery can also inhibit the growth and reproduction of malignant cells and reduce the recurrence rate of the disease. 3. Radiotherapy: receiving radiotherapy after breast cancer surgery can inhibit the growth and reproduction of local cells, which is also conducive to reducing the recurrence rate. It is recommended that patients go to the breast surgery department of the hospital, and the clinician will take into account the specific conditions of the patients and make personalized treatment plans.
