The Puncture Needle Of Breast Biopsy Needle Has What Advantage

The radical operation of breast cancer is a heavy blow to the patient both physically and psychologically, so it is necessary to make a definite diagnosis before surgery. There are many ways to diagnose breast cancer, including physical examination, mammogram, B ultrasound, MRI, etc., but the final diagnosis still relies on histopathological diagnosis (biopsy). Biopsy is the most commonly used means to obtain preoperative pathological diagnosis, which includes needle biopsy and surgical biopsy. Compared with surgical biopsies, needle biopsies cause less damage to normal tissue, have no scars, require only local anesthesia, and are relatively inexpensive. The most important thing is that needle biopsy can save some patients with benign breast lesions from unnecessary surgery. However, the method of simultaneous biopsy and surgical treatment is not conducive to the formulation of a detailed treatment plan before the operation and prolongs the operation time. In the case of malignant lesions, preoperative puncture needle biopsy not only provides basis for further treatment (including surgery and preoperative neoadjuvant chemotherapy), but also facilitates physicians and patients to jointly discuss surgical treatment modalities, such as whether to adopt breast preservation surgery. Therefore, before breast cancer surgery, puncture biopsy should be used as the standard procedure to evaluate the disease, and surgical biopsy is not encouraged for the preliminary evaluation of breast disease.
