If small nodules are found in the breast, do not worry too much. It is recommended to go to the breast surgery department of the local general hospital for a specialist examination, which requires color ultrasound and mammography of the breast. The incidence of nodules is very high, and many are caused by breast hyperplasia. If there are no symptoms, you can follow up and observe regularly. If there is no exclusion of the possibility of malignant transformation, further surgical treatment can be chosen to remove the lesion and perform pathological examination. If the lesion is confirmed to be malignant, it needs to be enlarged for radical excision. There are many patients who require adjuvant therapy after surgery, including systemic intravenous chemotherapy, endocrine therapy, and bioimmunotherapy.
