An ultrasound-guided breast biopsy is a minimally invasive breast biopsy that uses ultrasound guidance. We use a biopsy to determine if a mass we see within the breast is benign (noncancerous) or cancerous.
Ultrasound is an imaging tool that uses sound waves to produce images of breast tissue. A radiologist reviews these images and scans to distinguish various findings, looking for changes that may be as obvious as “masses” or as subtle as slight pulling of the tissue called “architectural distortion.” The findings on a breast ultrasound are often too small or deep to be felt on examination.
The best way for women to detect early changes in their breasts is to have regular screening mammograms, which often show areas of concern before they can be palpated during a clinical exam or breast self-examination (BSE). Further testing or a breast biopsy may be recommended if we discover a mass or architectural distortion during a screening.
Changes in breast tissue may lead to a doctor recommending a breast biopsy. Signs that may indicate breast tissue changes can include:
Masses
Lumps
Calcifications
Abnormal tissue
When a screening or test discovers an indeterminate or suspicious finding, the radiologist may recommend a breast needle biopsy to see if the mass is benign (noncancerous) or malignant (cancer). A lesion seen by ultrasound can be biopsied using ultrasound as a guide, even if it cannot be felt on clinical or self-breast examination. The physicians at The Women’s Imaging Center use their extensive clinical experience to determine the need for a breast biopsy.
We may recommend a breast biopsy if an abnormality is detected during a mammogram, ultrasound, or clinical breast exam. A biopsy is used to determine if the abnormality is cancerous or benign.
During a breast ultrasound biopsy, a small tissue sample is removed from the breast using a needle guided by ultrasound during a breast ultrasound biopsy. The procedure typically takes about 30 to 60 minutes and is performed under local anesthesia.
We begin by cleaning and numbing the area with a local anesthetic. A small incision is made, and a biopsy needle is inserted into the breast tissue. The ultrasound helps determine the precise location of the abnormality. A small tissue sample is removed and sent to a laboratory for examination.
A breast ultrasound may be recommended after a mammogram if there are any suspicious findings on the mammogram that need further evaluation. A breast ultrasound can provide more detailed images of the breast tissue and help identify abnormalities that may require additional testing or treatment.
