How you prepare

To prepare for your 3D mammogram:

• Choose a facility that offers 3D mammograms. Though 3D mammograms are becoming more common, they aren't available everywhere. If you're interested in this test, ask your doctor whether it's available in your area.
• Check with your insurance provider. Not all insurance companies cover 3D mammograms. Check with your insurance provider before your test so that you'll know what types of costs to expect. Your insurance company may cover the standard mammogram portion of the test, while you'll be responsible for the cost of the 3D mammogram portion.
• Schedule the test for a time when your breasts are least likely to be tender. If you haven't gone through menopause, that's usually during the week after your menstrual period. Your breasts are most likely to be tender the week before and the week during your period.
• Bring your prior mammogram images. If you're going to a new facility for your 3D mammogram, gather any prior mammograms and bring them with you to your appointment so that the radiologist can compare them to your new images.
• Don't use deodorant before your mammogram. Avoid using deodorants, antiperspirants, powders, lotions, creams or perfumes under your arms or on your breasts. Metallic particles in powders and deodorants can interfere with the imaging.
