Whether chemotherapy is needed after early surgical resection of breast cancer needs to be judged comprehensively according to the pathological results and whether there are contraindications to chemotherapy, etc. If there is no obvious lymph node metastasis, chemotherapy is generally not needed. Whether chemotherapy is needed in the early stage of breast cancer depends on the pathological results of the specimen, if it is only confined to the submucosal layer and there is no obvious lymph node metastasis, generally chemotherapy is not needed; if the pathology shows that it has broken through the basal layer or there is lymph node metastasis, chemotherapy is needed to inhibit the growth and reproduction of malignant cells; if it is a triple-negative breast cancer patient with the diameter of the tumor larger than 1 cm, chemotherapy is also needed even if there is no lymph node metastasis. Whether chemotherapy is needed in the early stage of breast cancer also needs to consider contraindications such as pregnancy, old age and infirmity. For patients with indication of adjuvant chemotherapy, postoperative radiotherapy is recommended to be carried out after completion of adjuvant chemotherapy; if there is no indication of adjuvant chemotherapy or individual patients with contraindication of adjuvant chemotherapy can start chemotherapy after postoperative incision healing and recovery of upper limb function. It is recommended to seek timely medical treatment, and the doctor will take into account the patient’s specific condition and develop a suitable treatment plan for the patient.
