There are many breast nodules, and the nature of the nodules needs to be clarified first. Benign nodules can usually be monitored regularly, and if there is a malignant tendency, appropriate surgical treatment or radiotherapy is needed. 1. Benign nodules: After BI-RADS examination, if the nodules are identified as category 1 to 3, they are mostly considered as benign nodules. There is no need for surgical treatment for the time being, but you should go to the hospital for regular checkups to observe whether the nodule has rapid growth or the possibility of malignant changes. At the same time, you need to pay attention to the regularity of life, emotional regulation, attention to balanced nutrition. 2. Malignant nodule: If the nodule is found to increase in size suddenly in regular checkups, or cause pressure on the surrounding tissues, timely surgery is needed. If the BI-RADS is grade 4 or above, there is a certain probability of malignant transformation, and the higher the grade number, the higher the possibility of malignant transformation. Timely surgery is needed, and the tissue should be taken for biopsy, and then treated by radiotherapy and chemotherapy. It is recommended that the patient should consult a doctor in time, do systematic examination and strictly follow the doctor’s instructions.
