How you prepare

By Mayo Clinic staff

Before the breast biopsy, tell your doctor if you:

  • Have any allergies
  • Have taken aspirin in the last seven days
  • Are taking blood-thinning medications (anticoagulants)
  • Are unable to lie on your stomach for an extended period of time

If your biopsy will be done using magnetic resonance imaging (MRI), tell your doctor if you have a cardiac pacemaker or other electronic device implanted in your body or if you're pregnant or think you may be pregnant. MRI generally isn't recommended under these circumstances.

Wear a bra to your appointment. Your health care team may place a cold pack against the biopsy site after the procedure, and the bra can hold the cold pack in place and provide support for your breast.
