A breast biopsy clip is a tiny, typically metallic marker placed within the breast during a biopsy procedure. It is left at the precise location where tissue samples were removed. This clip marks the biopsy site and is a routine, safe component of many procedures, designed to remain in the body without causing pain or harm.
Why Biopsy Clips Are Used
A biopsy clip serves several important functions. It marks the exact location of the biopsy site for future reference, ensuring the sampled area can be easily identified. This helps correlate pathology results with imaging findings, confirming the correct area was biopsied.
The clip is also essential if further medical intervention is needed. If the biopsy reveals abnormal or cancerous cells, the clip guides surgeons to precisely locate the area for subsequent surgical removal, especially when the abnormality is not palpable. The clip also aids in long-term monitoring by allowing radiologists to compare current and past images. This helps track changes or confirm the stability of a benign finding, potentially preventing unnecessary repeat biopsies. This is valuable when an abnormality might shrink or become invisible after treatments like chemotherapy, as the clip ensures the original site remains identifiable.
The Biopsy Clip Placement Procedure
Breast biopsy clip placement occurs as an integrated part of the biopsy procedure. It is performed immediately after tissue samples are collected, while imaging guidance (mammography, ultrasound, or MRI) is still in use. The clip is inserted through the same needle used to extract the tissue.
This step is quick and does not add significant discomfort. The breast area is already numbed with local anesthetic, so patients typically do not feel the clip insertion as a separate, painful event. While some pressure might be felt, sharp pain is uncommon due to the numbing medication. After placement, additional imaging, such as a mammogram or ultrasound, is often performed to confirm its correct position.
Understanding Biopsy Clip Materials and Types
Breast biopsy clips are very small, measuring 2 to 4 millimeters, comparable to a grain of rice or sesame seed. These markers are made from inert, medical-grade materials, most commonly titanium or surgical stainless steel. These materials are chosen because they are biocompatible, meaning they can safely remain within the body long-term without causing adverse reactions or rejection.
While the primary function of marking the biopsy site remains consistent, slight variations exist in clip shapes or designs. These differences do not alter the clip’s fundamental purpose. The materials ensure the clip is stable and does not degrade, providing a lasting reference point.
Living with a Biopsy Clip
Once placed, a biopsy clip remains permanently in the breast. It does not typically need removal unless surgical intervention on that specific site becomes necessary. These clips are visible on various imaging modalities, including mammograms, ultrasounds, and MRIs, serving as helpful markers for radiologists during future examinations.
Patients can safely undergo MRI scans, as these clips are MRI-compatible and do not interfere with imaging. Their minute size means they will not trigger airport security metal detectors. Most individuals do not feel the clip once placed due to its small dimensions and deep placement. While clips are designed to stay in place, minor shifts can occur, but they will not travel to other body parts.
