First, check with the place you are having the mammogram for any special instructions you may need to follow before you go. Here are some general guidelines to follow:

• Make your mammogram appointment for one week after your period. Your breasts hurt less after your period.
• If you have breast implants, be sure to tell your mammography facility that you have them when you make your appointment.
• Wear a shirt with shorts, pants, or a skirt. This way, you can undress from the waist up and leave your shorts, pants, or skirt on when you get your mammogram.
• Don’t wear any deodorant, perfume, lotion, or powder under your arms or on your breasts on the day of your mammogram appointment. These things can make shadows show up on your mammogram.
