    Breast ultrasound

    Ultrasonography of the breast; Sonogram of the breast

    Breast ultrasound is a test that uses sound waves to examine the breasts.

    How the Test is Performed

    You will be asked to undress from the waist up and put on a medical gown.

    During the test, you will lie on your back on the examining table.

    The doctor or nurse will place a gel on the skin on the breast.A hand-held device (called transducer) is rubbed over the breast area. You will be asked to raise your arms above your head and turn to the left or right as needed.

    The device sends sound waves to the breast tissue. The sound waves help create a picture that can be seen on acomputer screen.

    The number of people involved in the test will be limited to protect your privacy.

    Breast ultrasound may also be used to guide a needle during a breast biopsy.

    How to Prepare for the Test

    You may want to wear a two-piece outfit, so you do not have to completely undress.

    On the day of the test, do not useany lotions or powders on your breasts. Do not wear deodorant under your arms.

    How the Test Will Feel

    This test usually does not cause any discomfort.

    Why the Test is Performed

    Your doctor may order this test if you have:

    • A breast lump found during a breast exam
    • An abnormalmammogram

    A breast ultrasound can help:

    • Tell the difference betweena solid mass or a cyst
    • Look for a growth if you have clear or bloody fluid coming from your nipple

    Normal Results

    A normal result means the breast tissue appears normal.

    What Abnormal Results Mean

    Ultrasound can help show noncancerous growths such as:

    • Cysts -- fluid-filled sacs
    • Fibroadenomas -- noncancerous solid growths
    • Lipomas -- noncancerous fatty lumps that can occur anywhere in the body, including the breasts

    Breast cancers can also be seen with ultrasound.

    Follow-up tests to determine treatment may be needed:

    • Breast biopsy - ultrasound
    • Breast biopsy - stereotactic


    There are no risks associated with breast ultrasound. There is no radiation exposure.
