Which statement best describes why a post-biopsy clip might be used in follow-up imaging?

• A. To guide future surgical localization if the lesion recurs or is non-palpable
• B. To deliver adjuvant therapy
• C. To prevent infection
• D. To replace the need for imaging surveillance

Answer: (A)

A post-biopsy clip serves as a durable marker that marks the exact biopsy site on future imaging. This radiopaque landmark lets radiologists and surgeons locate the original lesion later, even if the lump has shrunk, changed, or is no longer palpable. When the lesion recurs or if a patient later presents with a non-palpable area, the clip guides precise localization for targeted excision or localization surgery, helping ensure the correct area is treated.

This tool isn’t used to deliver therapy or to prevent infection, and it doesn’t replace ongoing imaging surveillance. Regular follow-up imaging remains essential to monitor for any changes at the biopsy site or elsewhere in the breast.
