What should you know?
A newly felt breast lump is common and often benign, but it should be correlated with clinical examination and appropriate imaging. The first test depends on age, symptoms and individual risk.
Targeted ultrasound is often first in younger patients; diagnostic mammography is added according to age and clinical context. MRI or needle biopsy is reserved for selected questions.
Common symptoms and signs
- A new palpable lump or thickening
- Change in breast shape, skin or nipple
- Bloody nipple discharge
- A new axillary lump
Diagnosis and the role of ultrasound
Ultrasound distinguishes fluid-filled from solid masses and evaluates shape, margins, orientation and flow. Mammography is valuable for calcifications and broader structural changes, so the methods often complement each other.
- Cystic versus solid structure
- Shape, margins and tissue relationship
- Axillary lymph nodes
- Final BI-RADS category and recommendation
Treatment and next steps
Management follows the BI-RADS category and clinical-imaging agreement: routine screening, short follow-up, additional views or biopsy may be appropriate. A clearly suspicious palpable finding should not be ignored solely because one test is negative.
When is urgent care needed?
- Rapid growth or marked skin change
- Redness and high fever, especially during breastfeeding
- Bloody discharge or new nipple retraction
