Breast ultrasound is a test that uses sound waves to examine the breasts.
How is the Test 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 hand-held 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.
The number of people involved in the test will be limited to protect your privacy.
Preparation 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.
Why is the Test Performed?
Your provider may order this test if you have:
- A breast lump found during a breast exam
- An abnormal mammogram
- Clear or bloody nipple discharge
A breast ultrasound can:
- Help tell the difference between a solid mass or a cyst
- Help look for a growth if you have clear or bloody fluid coming from your nipple
- Guide a needle during a breast biopsy
Normal Results for Breast ultrasound
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 whether treatment may be needed include:
- Breast lump removal (lumpectomy)
- Open (surgical) breast biopsy
- Stereotactic (needle) breast biopsy
- Ultrasound-guided breast biopsy
Breast ultrasound Risks
There are no risks associated with breast ultrasound. There is no radiation exposure.
