Clip Placement
Clip placement also called a marker clip or tissue marker is a very common step during a breast biopsy—both core needle biopsy and vacuum-assisted biopsy (VABB).It helps radiologists and surgeons easily find the exact biopsy site in the future.
What Is a Breast Biopsy Clip?
A tiny marker (2–5 mm), usually made of titanium or stainless steel, sometimes with a biodegradable coating. It stays inside the breast permanently unless removed during surgery.
Why Is a Clip Placed?
- To mark the exact biopsy location: If the area shrinks or disappears after the biopsy (common with VABB), the clip shows where the sample was taken.
- In case further surgery is needed: If the biopsy shows cancer or atypical cells, the surgeon uses the clip to locate the area for removal.
- To help radiologists check stability over time: For benign findings, the clip helps compare future imaging.
How the Clip Is Placed ?
- After the biopsy samples are taken :The radiologist loads the clip into the biopsy device.
- The clip is inserted through the same needle: No new incision or needle is needed. It is placed at the exact spot where the tissue was sampled.
- Imaging confirms placement.
Usually a mammogram is taken right after the biopsy to confirm:
- The clip is positioned correctly
- It is visible on imaging
- Small bandage applied: No stitches are required.
Does Clip Placement painful?
No. The area is already numb from the biopsy, so you don’t feel clip insertion.
Is the Clip Safe?
Yes. The clip is:
- Biocompatible
- MRI-safe (does not cause heating)
- Does not set off airport metal detectors
- Does not cause allergies (even with metal sensitivity)
Can I feel the clip?
No. You cannot feel it inside the breast.
Does the clip ever move?
It may shift 1–2 mm as the tissue heals—this is normal and usually not clinically important.
