Which indication warrants a biopsy?

• A. Pain in the breast
• B. Persistent mass after aspiration
• C. History of breast cancer
• D. Age over 50

Answer: (B)

Choosing a biopsy after finding a persistent mass following aspiration is a clinically sound decision. This scenario indicates that, despite having undergone an initial procedure to remove fluid or tissue from the mass, the mass remains unchanged or continues to reappear. A persistent mass raises concern for underlying pathology that might not have been resolved by the aspiration, such as a neoplasm or a more serious condition. In the context of breast health, any persistent mass, especially one that does not resolve, warrants further evaluation and investigation, making biopsy a necessary next step to obtain definitive tissue for diagnosis.

The other indications, while they may prompt further investigation or monitoring, do not necessarily require a biopsy. Pain in the breast can have many benign causes and does not imply a need for biopsy unless accompanied by other worrisome findings. A history of breast cancer may require close surveillance, but it does not automatically necessitate a biopsy unless there are new concerning symptoms or findings. Lastly, age over 50 is a risk factor for breast cancer and may influence screening protocols, but it does not itself indicate the need for a biopsy. In summary, a persistent mass following aspiration is a direct indication for biopsy to rule out malignancy or other significant pathology.
