The results of a mammocentesis biopsy will in the vast majority of cases fall into one of two categories, benign breast lesions and malignant breast lesions. Mammography biopsy is the gold standard for the diagnosis of breast diseases. 1. Benign breast lesions include breast fatty adenoma, breast tissue hyperplasia, inflammatory breast lesions, etc. Benign lesions can be treated conservatively or surgically, and generally have no effect on the patient’s survival. 2. Malignant breast lesions mainly refer to breast malignant tumors. Early stage breast cancer without distant metastasis can be treated by surgery and supplemented with postoperative radiotherapy and neoadjuvant therapy, and generally has a better prognosis. On the other hand, advanced breast cancer is mainly aimed at prolonging the survival period of patients and has a poorer prognosis. Therefore, early detection of breast space-occupying lesions should go to regular hospitals as early as possible to get a clear diagnosis and avoid delay.
