Breast Ultrasound

A breast ultrasound is an imaging test that uses high-frequency sound waves as opposed to radiation, to look at the inside of your breasts. Ultrasounds also enable visualization of blood flow as well as differentiating between possible cancers as well as fluid-filled cysts.

The purpose of a breast ultrasound

Breast ultrasounds are often performed as follow up to a mammogram and may be used if you:

Have particularly dense breast tissue (Mammograms may not be able to see through dense tissue).
Are pregnant. Mammograms use radiation, but breast ultrasound scans do not. This ultimately makes it safer for the fetus.
Are younger than 25 years old.
