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. You will be given a gown to wear.
During the test, you will lie on your back on an examining table.
Your health care provider will place a gel on the skin of your breast. A handheld device, called a transducer, is moved over the breast area. You may be asked to raise your arms above your head and turn to the left or right.
The device sends sound waves to the breast tissue. The sound waves help create a picture that can be seen on a computer screen on the ultrasound machine.
The number of people involved in the test will be limited to protect your privacy.
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 your test, DO NOT use any lotion or powder on your breasts. DO NOT use deodorant under your arms. Remove jewelry from your neck and chest area.
How the Test will Feel
This test usually does not cause any discomfort, although the gel may feel cool.
