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. Although ultrasound-guided breast biopsy is minimally invasive, there is a risk of bleeding whenever the skin is penetrated.
Step-by-step of ultrasound-guided core-needle biopsy of the breast: review and technique
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. During this procedure, small samples of tissue are removed from the breast using a hollow needle. The needle is precisely guided to the correct location using ultrasound.
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.
Core needle biopsy uses a hollow needle to remove samples of tissue from the breast. A pathologist studies these samples under a microscope to see if they contain cancer. If they do, more tests will be done to help plan your treatment. Learn about factors that affect your prognosis and treatment. Before the procedure begins, your provider will use a small amount of local anesthetic to numb the skin and breast tissue around the suspicious area.
