If you have a lump in your breast or other changes in your tissue or nipple, an ultrasound may help determine the cause. 

A breast ultrasound is a type of imaging test that a doctor may order to check for tumours or other breast abnormalities. A breast ultrasound uses high-frequency sound waves to produce detailed images of the inside of your breast. 

To conduct a conventional breast ultrasound, a healthcare professional will use a handheld device called a transducer to create images of your breast.

Unlike X-rays and CT scans, ultrasounds don’t use radiation and are considered safe for pregnant people.
