Key findings

• A 5.3 × 5.3 mm well-defined hypoechoic nodule behind the nipple/areola, considered likely a small fibroadenoma.
  • BI-RADS 3: probably benign, not a cancer diagnosis. This category carries a malignancy likelihood of less than 2% and needs short-interval imaging follow-up rather than being ignored.
• A 3.7 × 1.9 mm elongated nodule at 4 o'clock, likely an intramammary lymph node.
  • BI-RADS 2: benign.
• No abnormal right axillary lymph nodes.

• Diffuse fibroglandular prominence with areas of parenchymal edema. The radiologist raises possible multifocal mastitis (breast inflammation/infection), and recommends a repeat ultrasound after treatment.
• Three small nodules at approximately 3, 9, and 10 o'clock are thought likely to be multiple small fibroadenomas.
  • BI-RADS 3: probably benign, follow-up required.
• An elongated nodule at 11 o'clock is likely an intramammary lymph node.
  • BI-RADS 2: benign.
• No abnormal left axillary lymph nodes.

What BI-RADS means

• BI-RADS 2: benign finding, routine care.
• BI-RADS 3: probably benign, usually monitored with a short-interval ultrasound. The ACR BI-RADS guidance defines this as “short-interval follow-up suggested”; the ACR notes the expected cancer likelihood is below 2%.

Practical next steps

1. See a breast surgeon, gynecologist, or treating clinician with this report, especially to assess for mastitis on the left.
2. If there is breast pain, redness, warmth, fever, nipple discharge, or a tender lump, seek review promptly because infection/inflammation may need treatment.
3. Complete the recommended follow-up ultrasound after treatment and at the interval your radiologist/clinician specifies. BI-RADS 3 lesions are commonly checked at about 6 months, but follow the report’s individualized plan.
4. Seek earlier review if a lump grows quickly, becomes hard/fixed, skin or nipple changes occur, bloody nipple discharge develops, or you have persistent symptoms.
