Women’s Imaging: Breast Ultrasounds

Breast ultrasound is another non-invasive test used by doctors to evaluate breast cancer. It is generally recommended when:

• A doctor feels a lump in the breast during a clinical examination.
• Further evaluation of an abnormality found on a screening or diagnostic mammogram is needed.
• To help differentiate between a solid breast mass and a fluid-filled cyst.
• To evaluate the cause of spontaneous nipple discharge.
• To assess breast tissue in symptomatic women under 30.
• As a supplement to screening mammography for patients with dense breasts.
• For women who are pregnant in order to avoid radiation exposure.
• To evaluate areas of the breast that can be difficult to see with a mammogram, such as the areas close to the chest wall.

Are Breast Ultrasounds Harmful?

Ultrasound uses harmless sound waves to generate images of the inside of the breast. These waves pass through the breast and bounce back, or echo, from the tissues within the breast. A computer translates the echoes into images on a screen, which are then used by a doctor to arrive at a diagnosis.

Preparing for a Breast Ultrasound

• Avoid the use of powders, lotions or cosmetics on your breasts the day of your examination.
• Wear comfortable clothing that can be easily removed.
• Avoid wearing jewelry to your examination or be sure that it can be easily removed.
