  1. What is a biopsy marker made of?
    • The markers we use are made of stainless steel or titanium
  2. How does a marker help if I need surgery?
    • The marker marks the site of the biopsy within the breast. If your biopsy results require surgery, the marker helps the radiologist and/or surgeon localize the area to be surgically removed. This will also help them remove the least amount of tissue during surgery
  3. What is the purpose of the marker if I don’t need surgery?
    • If surgery is not required, it marks the site of the biopsy within the breast. This allows radiologists reading your future mammograms know that a biopsy has been done
  4. How does a biopsy marker get placed?
    • Through the same incision and sterile hollow needle that is used to perform your biopsy, while your breast is still numb. Most people are surprised to learn that it is already in place!
  5. How will this affect my daily life?
    • Short answer: it will not!
    • Long answer:
      • It cannot be felt, because it is inside the breast tissue
      • It will not set off airport alarms or metal detectors
      • The marker is MRI compatible, if you ever need an MRI
      • The marker is not a tracking device!

A biopsy marker has almost zero risk and offers your radiologists and surgeons invaluable information.
