How you prepare

To prepare for your mammogram:

• Schedule the test for a time when your breasts are least likely to be tender. If you menstruate, that's usually during the week after your menstrual period.
• Bring your prior mammogram images. If you're going to a new facility for your mammogram, request to have any prior mammograms placed on a CD. Bring the CD with you to your appointment so that the radiologist can compare past mammograms with 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 could be visible on your mammogram and cause confusion.
