Breast Ultrasound

A breast ultrasound is often used as a follow-up test after an abnormal mammogram or when a lump has been found. MaineHealth has the expertise you need when it comes to diagnosing abnormal breast changes.

What is a breast ultrasound?

A breast ultrasound can examine most abnormal breast changes or mammogram results.  It uses sound waves to make a picture of the breast so doctors can get a closer look at any changes that may have been identified from a mammogram. It can determine the exact size, location whether a lump is a solid mass or a fluid-filled cyst, and can provide an imaging guide for a biopsy.

What happens during a breast ultrasound?

Gel is placed on the breast and on a hand held device called a transducer that is moved over the skin to show the tissue beneath.  Sound waves are sent out that pick up echoes from the tissue; these are made into images on a computer screen that a doctor reviews. There is no pain during this test, and it does not use any radiation.
