What need notice after mammary gland biopsy needle

Commonly used breast biopsies include needle aspiration biopsy, excision biopsy and excision biopsy. The operation of needle aspiration biopsy is as follows: a small incision is made under the local anesthesia of the skin at the puncture site, a thick needle or a puncture needle with a needle core is inserted, and a small piece of tissue is sucked out for pathological examination. Or use a trephine to draw materials. Needle aspiration or trephine biopsy has the advantage of less trauma, but the reliability of pathological diagnosis is inferior to excision or excision biopsy due to the small amount of tissue removed. Generally speaking, if the diameter of the mass is less than 2cm and the possibility of benign is high, excision biopsy should be performed, that is, the whole mass and surrounding tissues should be excised for paraffin section examination. For patients with large diameter and high suspicion of malignancy, biopsy is feasible, that is, under the preparation of radical surgery, part of the tissue is cut from the hardest part of the tumor for frozen section examination, and part of the tissue is retained for paraffin section.
