Breast ultrasound uses sound waves that cannot be heard by humans to look at the breast.

Alternative Names

Ultrasonography of the breast; Sonogram of the breast

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.

A water-soluble gel is placed on the skin of the breast. A hand-held device (transducer) directs the sound waves to the breast tissue. The transducer is moved over the skin of the breast to create a picture that can be seen on a screen.

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

How to prepare for the test

Because you need to remove your clothing from the waist up, it may be helpful to wear a two-piece outfit. On the day of the test, do not use any lotions or powders on your breasts or wear deodorant under your arms.

How the test will feel

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

You will be asked to raise your arms above your head and turn to the left or right as needed.

There is no discomfort from the ultrasound.

Why the test is performed

Common uses of ultrasound are:

  • In addition to a mammogram or physical exam, if something abnormal is found. If a mammogram shows a growth, ultrasound can help determine whether it is a solid mass or a cyst.
  • By itself, to check a breast lump or nipple discharge
Normal Values

Normal breast tissue.

Normally, the breast tissue will be uniform and will not have any suspicious growths.

What abnormal results mean

Ultrasound can help show noncancerous growths such as cysts, fibroadenomas, or lipomas. A cyst is a fluid-filled sac. A fibroadenoma is a noncancerous solid growth. Lipomas are noncancerous fatty lumps that can occur anywhere in the body, including the breasts.

Breast cancers can also be seen with ultrasound.

What the risks are

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

Why the test is performed

If a breast lump is found during an exam or something abnormal is seen on your mammogram, an ultrasound can help show whether it is a solid mass or a cyst. It can also be used to check for a growth in the breast if a woman has clear or bloody nipple discharge.

Normal Values

Normally, the breast tissue will look the same and will not have any suspicious growths.

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.

Do a mammogram and ultrasound always catch breast cancer?

Mammogram and ultrasound can't catch every abnormal or cancerous cell in the breast, but they do a good job of detecting important groups of abnormal cells. Talk with your health care provider if you feel you are at higher risk of breast cancer. Your provider may be able to discuss strategies for screening and risk modification.
