Does ultrasound require a biopsy for a benign breast mass? Clinically, such patients are often encountered. Mammography examination reveals local or blurred masses. Ultrasound examination is considered benign. Is it safe to ask for a biopsy follow-up? Is there a possibility of breast cancer missed? Australian scientists conducted a study in which 448 women, 448 breast lumps that met the above conditions were biopsied after mammography and ultrasonography, and 488 tumors were actually followed for 445 (3 fibers) Adenoma). Follow-up results showed that there were no changes in 442 tumors, two tumors were enlarged (biopsy pathology was fibroadenomas), and one developed into cancer. The false negative rate was 0.2% and the negative predictive value (NPV) was 99.8%. Therefore, the investigators believe that because of the high NPV of the ultrasound examination, the ultrasound examination is considered to be a benign breast mass, and follow-up can be used as an alternative to needle biopsy. ——Midi Medical Network
