What should you know?
A simple cyst is fluid-filled, while a fibroadenoma is a solid benign mass. Typical ultrasound features help distinguish them, but atypical lesions require further assessment.
Breast ultrasound evaluates a lump, cyst, focal pain and axillary lymph nodes. Depending on age and symptoms, it may be the first test or an adjunct to mammography.
Common symptoms and signs
- Fluid and posterior enhancement in a simple cyst
- Often oval parallel shape of a fibroadenoma
- Wall, internal tissue and blood flow
- Growth and age-related risk
Diagnosis and the role of ultrasound
The radiologist documents shape, margins, orientation, contents and vascularity and may assign a BI-RADS category. Ultrasound does not always replace mammography or biopsy.
- Solid or fluid-filled character
- Shape, margins and orientation
- Vascularity and surrounding tissue
- Appearance of axillary lymph nodes
Ultrasound findings must be interpreted together with symptoms, examination and, when needed, laboratory or other imaging results. An image alone should not be used for self-diagnosis or self-treatment.
Treatment and next steps
A simple cyst often needs no treatment; a growing or suspicious solid mass may need follow-up or biopsy. Management follows the BI-RADS category and clinical risk and may include routine screening, short-interval follow-up, mammography or biopsy.
Management is individual and depends on age, symptoms, imaging findings, other health conditions and pregnancy plans. Medication or a procedure should be selected with the appropriate clinician.
When is urgent care needed?
- A new hard or rapidly enlarging lump
- Skin retraction, bloody nipple discharge or new nipple inversion
- Redness and warmth accompanied by high fever
