Advantages and Challenges of Using Breast Biopsy Markers.

Percutaneous image-guided biopsy procedures are the standard of care for histologic assessment of suspicious breast lesions. Post-biopsy tissue markers (clips) optimize patient management by allowing for assessment on follow-up imaging and precise lesion localization. Markers are used to ensure accurate correlation between imaging modalities, guide preoperative localization for malignant and high-risk lesions, and facilitate accurate identification of benign lesions at follow-up. Local practices differ widely, and there are no data detailing the exact frequency of use of clips for different breast biopsies. There are many indications for biopsy marker deployment, and some difficulties may be encountered after placement. The placement of biopsy markers has many advantages and few disadvantages, such that deployment should be routinely used after percutaneous biopsy procedures with rare exception.
