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

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.

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.

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.

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.
