A breast ultrasound uses sound waves to image the breast. A breast ultrasound is usually performed to further analyze an abnormality seen on a mammogram. They are also used to image lumps that can be felt.  Breast ultrasounds can help determine the need for a biopsy or additional testing. 

Breast Ultrasound is currently not recommended for breast cancer screening in the general population. It is not covered by insurance as a screening exam and will require a charge if desired for the purpose of screening.
