What Does A Biopsy Needle Mean

Biopsy is an examination method to determine the nature of the diseased tissue. Part of the tissue is obtained by fine needle aspiration, resection and other methods at a certain location of the living human body for pathological examination, so as to confirm the diagnosis and carry out subsequent treatment.

Biopsy, known as biopsy, refers to the technique of removing diseased tissue from a patient's body for pathological examination by cutting, forceps or puncture according to the needs of diagnosis and treatment.

Biopsy, including fine needle aspiration biopsy and lymph node biopsy, is of great clinical significance. Fine needle aspiration biopsy is mainly used to puncture liver and lung tumors. Under local anesthesia, a little tumor tissue is hooked out for cytology, and the cell morphology and structure of the tissue are observed under the microscope to make a clear diagnosis. Lymph node biopsy is mainly performed for superficial lymph nodes in the neck, axilla and groin areas. Some lymph nodes are removed under local anesthesia and pathological examination is performed.

Before biopsy, keep an empty stomach to avoid high fat content, which may affect the examination results. At the same time, it is necessary to pay attention to the week before the biopsy to prevent infection.
