What Is a Breast Ultrasound?

Breast ultrasound is a medical imaging technique used to examine the breast. A physician may order this test to obtain more information about a palpable lump or other abnormal structures, or when mammography is unsuitable for the patient. During the procedure, a technician or physician moves a handheld transducer over the breast to emit high-frequency sound waves. As these waves bounce back from internal tissues, the transducer detects and records them, generating real-time images of the breast’s internal structures.

What Is Breast Ultrasound?

Breast ultrasound is an imaging modality that uses sound waves to evaluate the breast for potential abnormalities or pathology. Generally, no special preparation is required prior to the exam. The patient lies supine on the examination table with both breasts and axillae fully exposed to allow comprehensive scanning.

Ultrasound can detect numerous breast conditions, including fibrocystic changes (breast hyperplasia), breast cysts, and solid breast masses. When a mass is identified, ultrasound can help characterize and categorize it—assessing whether it exhibits features suggestive of benignity or malignancy. For instance, a mass with well-defined margins, regular shape, and homogeneous internal echotexture is typically considered benign and may be managed with routine follow-up surveillance. Conversely, a mass exhibiting markedly hypoechoic appearance, ill-defined or irregular margins, and posterior acoustic shadowing raises concern for malignancy and warrants further diagnostic evaluation—such as biopsy—or referral to a surgeon for possible excision.

Prior to ultrasound, clinicians may recommend this modality to enhance image clarity—particularly in patients with extremely dense breast tissue or large breast implants, which can obscure visualization of glandular structures on mammography. Although mammography remains the gold standard for early detection of breast abnormalities, it may provide limited diagnostic utility in certain women. In such cases, breast ultrasound offers a valuable complementary or alternative imaging option.
