Breast puncture is generally an examination method used to collect samples of pathologic tissue for pathological examination and is commonly used to diagnose diseases and treat illnesses, among other things. Breast puncture is a method of biopsy. It is commonly used for patients with lumps of unknown nature in the breast. Through breast puncture biopsy, the collected nodule tissue can be pathologically examined to determine the benign or malignant nature of the nodule, which will help to confirm the final diagnosis. In addition, when a patient with mastitis has a breast abscess, breast puncture can also be used to drain the pus, which can be useful in relieving the inflammation of the breast. This puncture method is usually performed under local anesthesia, which is less traumatic to the patient and more helpful in the diagnosis and treatment of breast diseases. It is recommended that patients with breast discomfort consult a regular hospital in time and standardize the treatment under the guidance of the doctor.
