Test Overview A breast ultrasound uses sound waves to make a picture of the tissues inside the breast. A breast ultrasound can show all areas of the breast, including the area closest to the chest wall, which is hard to study with a mammogram X-rays
A breast ultrasound is used to see whether a breast lump is filled with fluid (a cyst
For a breast ultrasound, a small hand-held unit called a transducer
Why It Is Done
Breast ultrasound can add important information to the results of other tests, such as a mammogram or magnetic resonance imaging (MRI)
Find the cause of breast symptoms, such as pain, swelling, and redness. Check a breast lump found on breast self-examination or physical examination. It is used to see whether a breast lump is fluid-filled (a cyst) or if it is a solid lump. A lump that has no fluid or that has fluid with floating particles may need more tests. Check abnormal results from a mammogram. Look at the breasts in younger women because their breast tissue is often more dense, and a mammogram may not show as much detail. Guide the placement of a needle or other tube to drain a collection of fluid (cyst abscess biopsy Watch for changes in the size of a cyst or a non-cancerous lump (fibroadenoma). See how far cancer has spread in a breast. Check your breasts if you have silicone breast implants or dense breasts. In these situations, a mammogram may not be able to see breast lumps.

How It Is Done
You will be asked to undress above the waist. You will be given a gown to drape around your shoulders. Remove all jewellery from around your neck.
Gel will be put on your breast so the transducer can pick up the sound waves as it is moved back and forth over the breast. A picture of the breast tissue can be seen on a TV screen.
How long the test takes A breast ultrasound test usually takes 15 to 30 minutes. More time may be needed if a breast exam will be done or if a biopsy is also planned. You may be asked to wait until a radiologist
How It Feels
The gel may feel cold when it is put on your breast. You will feel light pressure from the transducer as it passes over your breast, but you should feel no discomfort unless your breast is tender because of fibrocystic breast changes
Risks
There are no known risks from having this test.
