Breast Ultrasound

Ultrasound, or sonography, produces images of the breast by generating high-frequency sound waves. As the sound waves bounce off breast tissues, they create echoes. A computer then translates these echoes into images on a screen, images that can show abnormalities (disease) within the breast. The process is fast, painless and completely free of radiation or harmful side effects.

There are two primary uses for breast ultrasound:

To determine the nature of a breast abnormality

In this case, breast ultrasound is used to help diagnose breast abnormalities detected by a physician during a physical exam (such as a lump or spontaneous clear nipple discharge) and to characterize potential abnormalities seen with a mammogram. With ultrasound, it is possible to determine if the abnormality is a non-cancerous (benign) lump of tissue or a cancerous (malignant) tumor.

Supplemental breast cancer screening

Although mammography is the only screening tool for breast cancer that is known to reduce deaths due to early detection, it does not detect all breast cancers. Some breast lesions and abnormalities are not visible or are difficult to interpret on mammograms, especially in breasts that are dense. Screening ultrasound can be an alternative to breast MRI in some cases, such as women with implants, women who are pregnant, or women who may be unable or unwilling to have a breast MRI performed.

For breast ultrasound, no special preparation is needed.
