A Breast Biopsy Marker Before MRI: What to Tell the Team
Menopause & HormonesArticleTell the MRI team about your existing marker and let them complete the safety check.

In this article
If an MRI appointment has you wondering about the marker left after your breast biopsy, tell the MRI team about it. Cambridge University Hospitals says these markers identify an area sampled during a biopsy and are unlikely to prevent MRI. That does not replace your own safety check.1
Start with the marker
Try: “I have a marker from a breast biopsy. What information do you need about it before my scan?”1
Keep the question with your appointment details so you remember to raise it.1
Let the team check the wider picture
CUH explains that MRI uses powerful magnets and is not suitable for everyone. Its radiographer goes through a safety checklist. Mention other implants, devices or relevant operations when the team asks; do not assume the answer about a biopsy marker covers another device.1
Try: “Could we confirm that my marker and other medical history have been included in the safety check?”1
My Body Changed. Now What? includes a Visit Brief. Use it to keep your scan question ready for the appointment. See the book.
