Ultrasound uses sound waves to generate a picture of the breast tissue. No compression is necessary.
Ultrasound is particularly useful in telling cysts from solid masses in the breast. Cysts are very common and totally benign; about half of all women have some cysts in their breasts at some point. Ultrasound is also very helpful in characterizing masses and lumps.
What happens if they find something in my breast?
Sometimes we do find a lesion that requires a biopsy to find out what it is. Fortunately, the vast majority of breast biopsies can be accurately performed with a needle and do not require surgery. Depending on the finding, a needle biopsy is performed, using either stereotactic (mammogram), ultrasound, or MRI guidance. Most breast biopsies are negative and no further follow-up is required.
