What procedure is recommended for a non-palpable mass detected on a mammogram?

• A. Surgical excision
• B. Stereotactic biopsy
• C. Open biopsy
• D. Fine needle aspiration

Answer: (B)

The recommended procedure for a non-palpable mass detected on a mammogram is a stereotactic biopsy. This technique is particularly valuable because it allows for the precise targeting of a mass that cannot be felt during a physical examination. Stereotactic biopsy utilizes advanced imaging technology to guide a needle to the exact location of the mass, enabling the collection of tissue samples for pathological examination.

This method is minimally invasive compared to surgical excision or open biopsy, reducing both the recovery time and the risks associated with more extensive surgical procedures. Additionally, stereotactic biopsy can often be performed on an outpatient basis, further enhancing patient convenience and comfort.

Fine needle aspiration, while useful in certain circumstances, may not provide a conclusive diagnosis for a non-palpable mass, particularly if the lesion is small or has a complex architecture that requires a larger tissue sample to assess accurately. This makes stereotactic biopsy a more advantageous choice for obtaining the necessary diagnostic information in such cases.
