A breast ultrasound uses sound waves to create pictures of breast tissue. It can help assess a change such as a lump and may show whether an area appears fluid-filled or solid. The meaning of a finding, and whether another test is needed, depends on the full clinical context.[3]
Do not delay assessment of a new breast change
A new breast or armpit lump, concerning skin or nipple change, or other persistent change needs prompt medical assessment. NICE sets referral recommendations according to the person’s age and findings; this guide cannot decide the right route for you.[2]
When ultrasound may be used
A breast clinic may use examination, mammography, ultrasound and, where needed, biopsy. Not everyone needs every test. NHS guidance describes these as parts of an assessment pathway for symptoms or an abnormal screening result.[1]
What ultrasound cannot do alone
Ultrasound is not a standalone diagnosis or a replacement for the NHS breast-screening programme. A normal or abnormal scan needs to be interpreted with symptoms, examination and any other imaging. If a finding needs more assessment, the next step may include breast-clinic review or another test.
Before and during the scan
Preparation and the examination route vary. At booking, the clinic confirms suitability, preparation, availability, reporting and follow-up. You can ask questions, request adjustments for privacy or comfort, and pause or stop the examination.
Results and follow-up
How and when results are discussed depends on the pathway and whether further assessment is needed. The clinic confirms its reporting route at booking; an imaging result does not substitute for urgent assessment of persistent or worsening symptoms.
