Breast ultrasound
Informed by recognized medical guidance
Overview
A breast ultrasound is a safe, painless imaging test that uses sound waves to create pictures of the inside of your breast. It helps doctors see whether a lump or area of concern is a fluid-filled cyst (usually harmless) or a solid mass that may need further testing.
Key facts
- Breast ultrasound does not use radiation, so it is very safe.
- It is often used after a mammogram to get a closer look at an area.
- It can help tell the difference between a fluid-filled cyst and a solid lump.
Breast ultrasound is a common test used worldwide for women (and some men) with breast symptoms or abnormal mammogram results.
It is most often used for women, especially those under 40 with dense breast tissue. It may also be used for pregnant or breastfeeding women, or for men with breast symptoms.
