About this procedure
Breast ultrasound uses sound waves to examine tissue within the breast. It can help clarify the nature of lumps and changes found during an examination or on another test, but it is not a complete replacement for mammography in screening programs.
The clinician moves a gel-covered transducer over the breast and, when appropriate, nearby regions and regional lymph nodes. The report describes the location, structure and appearance of visible findings.
Special preparation is not usually required. Bring earlier images or reports. Whether a particular day of the menstrual cycle is preferred for a specific question can be discussed individually; do not postpone assessment of concerning symptoms to fit the calendar.
Not every lesion is visible on ultrasound. Mammography remains a key screening tool for many age and risk groups. A suspicious finding may require a biopsy, which is a separate procedure.
The results are documented in a medical report describing the structures seen and any limitations. Follow-up is determined by an appropriate clinician according to symptoms and findings. One ultrasound feature is not necessarily a definitive diagnosis and should not prompt self-treatment. Earlier reports can help compare repeat examinations, although measurements may vary with technique and circumstances.
Signs and symptoms
- A palpable lump, localized changes or pain when a clinician recommends scanning.
- Further assessment of findings detected by mammography or breast MRI.
- Monitoring of previously identified changes according to an agreed plan.
Diagnosis and tests
The clinician scans the breast with a gel-covered transducer and may examine adjacent tissues and regional lymph nodes. The location, structure and appearance of visible findings are recorded.
Not every lesion can be detected by ultrasound. Mammography remains essential for screening in many groups, and a suspicious finding can require biopsy as a separate procedure.
Care and treatment approaches
Ultrasound is diagnostic imaging, not treatment. Further consultations, tests or repeat scans depend on the clinical findings. Do not start medicines or procedures solely on the basis of a scan result.
When to seek urgent care
A new breast lump, bloody nipple discharge or changes in breast shape or skin warrant timely medical assessment. Fever with rapidly increasing painful redness and swelling requires urgent evaluation.
Frequently asked questions
Does ultrasound replace mammography?
No. The tests complement each other. The choice depends on age, symptoms and individual risk factors.
Can an ultrasound show a cyst?
It can often distinguish a fluid-filled lesion from a solid one, although the interpretation depends on all the findings.
Can I have a scan without preparation?
Yes, special preparation is usually unnecessary. Bring previous results for comparison.
Important information
A medical consultation is needed for diagnosis and treatment recommendations.
Self-treatment can be harmful to your health.
