Medical Markers in the Breast: What Patients Need to Know About Biopsy Clips > 자유게시판

Breast biopsy clips are small medical markers placed in breast tissue during a biopsy to mark the exact site sampled, and they play an important role in diagnosis, follow-up imaging, and surgical planning for both benign and malignant findings[2][5].

What a biopsy clip is and why it’s used

A breast biopsy clip (also called a breast marker) is a tiny (typically 2–3 mm) biocompatible marker, often metallic but increasingly available in biodegradable or composite materials, that is left at the location where tissue was sampled during a percutaneous breast biopsy[1][4][5]. The clip makes the biopsy site visible on future imaging (mammography, ultrasound, and sometimes MRI) so radiologists and surgeons can reliably find the area again without re-biopsying or unnecessarily removing additional tissue[2][3][5].

How clips are placed and what patients experience

Clips are usually placed immediately during the biopsy procedure through the same needle tract; placement is quick and adds minimal time to the procedure[3]. Patients typically do not feel the clip once it is in place and the markers do not cause pain or harm, according to standard clinical descriptions[2]. Clips are left in place when a biopsy is benign to enable follow-up imaging of that exact spot; if pathology shows cancer or atypia, the clip also serves as a guide for preoperative localization and surgical planning[5][2].

Types of markers and technological developments

Markers vary by design and material: traditional metallic clips (titanium or stainless steel) are common, while more recent innovations include clips combined with hydrogels, collagen, polymers, or fully biodegradable materials to improve visibility on ultrasound/MRI and reduce migration[5][4]. Some hydrogel-containing markers (for example, devices that use PEG-based hydrogels) provide prolonged ultrasound visibility for many months, assisting follow-up imaging[5]. Research and product development continue to focus on optimizing visibility across imaging modalities and minimizing long-term issues[4][5].

Safety, MRI compatibility, and potential concerns

Regulatory and clinical reviews indicate that biopsy markers are generally safe and well tolerated, and many modern devices are considered MRI-conditional rather than MRI-unsafe[6][5]. Early concerns about ferromagnetism, heating, or image artifacts have been addressed by testing and by the development of MRI-compatible designs, though clinicians remain mindful of which specific device was placed when ordering MRI[6][5]. Marker migration (movement from the original site) is uncommon but recognized; some manufacturers incorporate design features (collagen, netting, or polymer pads) to minimize migration and improve sonographic visibility[5]. Biodegradable markers are being studied as alternatives that may not require long-term retention in tissue[4].

Implications for patient care and communication

The presence of a clip should be documented in the radiology report and communicated to the patient and surgical team when relevant, because it affects future imaging interpretation and any surgical approach[5][2]. For patients, knowing that a clip marks the previously sampled area can reduce anxiety by clarifying why repeat imaging targets that specific spot and by preventing unnecessary repeat biopsies when prior results were benign[3][5]. If you have questions about a clip placed during your care—its type, MRI compatibility, or whether it will be removed—ask your radiologist or breast surgeon; they can reference the device used and web page explain follow-up plans[5][6].

Clinical evidence and standards

Biopsy marker use became established as percutaneous breast biopsy techniques evolved, and standardization of marker nomenclature and testing has been an ongoing area of clinical attention[5]. Regulatory approval for biopsy markers in soft tissues dates back to the mid-1990s, and evidence supporting marker safety and utility is reflected in clinical reviews and device research[5][2][4]. Current literature and product information emphasize choosing markers that balance long-term visibility for imaging, minimal artifact for MRI, and low migration risk[5][6].

Practical takeaways for patients

• A clip is a small, standard medical marker placed during biopsy to mark the sampled spot for future imaging and surgery[2][1].
  
• Clips are usually painless, safe, and commonly left in place when biopsies are benign; they help avoid repeat procedures and guide treatment if needed[3][5].
  
• If you may need MRI later, confirm with your care team which marker was used and whether it is MRI-conditional to avoid unexpected image artifacts or precautions[6][5].
  
• Advances include biodegradable and hydrogel-enhanced markers designed to improve imaging visibility and reduce the need for permanent metallic implants[4][5].
