Patients with triple-negative breast cancer can prevent recurrence through postoperative adjuvant chemotherapy, adjuvant radiation therapy, and regular monitoring. Triple-negative breast cancer is a highly malignant type of breast cancer. Apart from surgery, radiotherapy and chemotherapy, endocrine and targeted drug therapy is not suitable. Therefore, this molecular type of breast cancer is prone to postoperative recurrence. In order to reduce the incidence of recurrence, the following methods can be adopted: 1. 1. Postoperative chemotherapy. Regardless of the surgical method, patients with triple-negative breast cancer need to be treated with chemotherapy after surgery to reduce recurrence. 2. If the patient has breast-conserving surgery, radiation therapy for the whole breast cancer should be given after surgery, which can significantly reduce the risk of local recurrence. 3. Post-operative patients need to undergo regular follow-up to monitor the development of the disease, which mainly includes ultrasound examination of the breast and axillary lymph nodes, and examination of tumor markers such as carcinoembryonic antigen and glyco-antigen 153.
