How you prepareBy 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.
