The cure rate for invasive breast cancer grade 3 is usually 40% to 70% and varies depending on the presence of lymph node metastases, tumor size, and the presence of distant metastases. Clinically, if there is no recurrence after 5 years of treatment, it is usually called clinically cured. For invasive breast cancer grade 3, if the tumor is detected early, the tumor is staged early, there is no metastasis of lymph nodes and distant metastasis, after active treatment, the cure rate can reach 40% to 70%. At present, the effect of simple surgical resection is not good, and it should be combined with radiotherapy, chemotherapy, targeted drugs and other comprehensive treatment. Since invasive breast cancer patients are diagnosed relatively late, they should be actively treated at this time. Radical excision is adopted in preoperative preparation, and chemotherapy, endocrine therapy and radiotherapy are assisted after the surgery to prevent recurrence and metastasis after the surgery and improve the cure rate. It is recommended that patients follow the doctor’s instructions for treatment after diagnosis, so as to achieve early detection and early treatment, and regular follow-up after surgery, usually the cure rate will also be significantly improved.
