Breast puncture is a common examination method, which usually involves inserting a thin needle into the breast under local anesthesia to remove part of the tissue out of the body, after which it is sent for pathological examination so that the pathologist can see if there are cancerous cells in the tissue. If no malignant cells are found, patients do not need to worry too much and just go to the hospital for regular review. However, if cancer cells are found, it is necessary to further improve the relevant examination, perform radical resection of tumor, and then cooperate with lymph node dissection, and give chemotherapy, targeted drug therapy, endocrine therapy, radiotherapy and traditional Chinese medicine treatment at the later stage. After puncture, local pressure can be applied for a period of time to prevent bleeding. At the same time, alcoholic beverages should not be consumed for a short period of time, and overly strenuous exercise should not be done. Other precautions can be taken by consulting with a competent physician.
