To review the role of ultrasound-guided core-needle biopsy CNB in the management of breast lesions. This technique shows a high sensitivity value of about All of these advantages have made this technique the most widespread used to perform a biopsy for a suspicious breast lesion.
A breast biopsy is a test that removes tissue or sometimes fluid from the suspicious area. The removed cells are examined under a microscope and further tested to check for the presence of breast cancer. A biopsy is the only diagnostic procedure that can definitely determine if the suspicious area is cancerous.
Ultrasound-guided breast biopsy is a minor procedure. The radiologist places an ultrasound probe over the site of the breast abnormality, and using local anesthesia, guides a biopsy needle directly into the mass. Multiple tissue specimens are then taken using a hand-held biopsy device.
Ultrasound-guided core-needle biopsy has high sensitivity in the diagnosis of breast cancer. The present study is aimed at detailing the main steps of such procedure, including indications, advantages, limitations, follow-up and description of the technique, besides presenting a checklist including the critical steps required for an appropriate practice of the technique. In the recent years, an increasing number of patients have required breast biopsy, indicating the necessity of a proportional increase in the number of skilled professionals to carry out the procedures and histological diagnoses. A multidisciplinary approach involving the tripod clinical practice-radiology-pathology is responsible for the highest rate of accuracy of the technique and must always be adopted.
Based on the results of your last breast ultrasound or mammogram, your physician has recommended a breast biopsy in order to obtain further information. A biopsy is a procedure in which a small sample of tissue is taken for further examination by the laboratory. There are different types of biopsies; this type is an ultrasound-guided biopsy.
An ultrasound-guided breast biopsy uses sound waves to help locate a lump or abnormality and remove a tissue sample for examination under a microscope. It is less invasive than surgical biopsy, leaves little to no scarring and does not involve exposure to ionizing radiation. Tell your doctor about any recent illnesses or medical conditions and whether you have any allergies, especially to anesthesia.
This procedure is also called wire localisation followed by surgical biopsy or wire guided excision biopsy. A wire guided excision biopsy means putting a wire into the breast tissue to show a surgeon which piece to remove. This procedure is used if a breast x-ray mammogram or ultrasound has shown an abnormal area but the doctor can't feel a lump.
The doctor doing the CNB may put the needle in place by feeling the lump. But usually the needle is put into the abnormal area using some type of imaging test to guide the needle into the right place. Some of the imaging tests a doctor may use include:.
For a breast biopsy, breast tissue may be removed with a special biopsy needle. Or it may be removed during surgery. To check a problem seen on a mammogram, such as small calcium deposits in breast tissue microcalcifications or a fluid-filled mass cyst.
A breast biopsy is the removal of breast tissue to examine it for signs of breast cancer or other disorders. There are several types of breast biopsies, including stereotacticultrasound-guided, MRI-guided, and excisional breast biopsy. This article focuses on needle-based, ultrasound-guided breast biopsies.
