Mammography is an X-ray exam of your breast tissue. The image it makes is called a mammogram. A mammogram can help find problems with your breasts, such as cysts or cancer. Mammography is the best breast cancer screening tool available.


Have screening mammograms and professional breast exams as often as your healthcare provider recommends. Also, be sure you know how your breasts normally look and feel. This makes it easier to notice any changes. Report changes to your healthcare provider as soon as possible. 

How do I get ready for a mammogram? 

  • Schedule the test for 1 week after your period. Your breasts are less sore then.

  • Make sure your clinic gets images of your last mammogram if it was done somewhere else. This lets the provider compare the 2 sets of images for any changes.

  • On the morning of your test, don’t use deodorant, powder, or perfume.

  • Wear a top that you can take off easily.

What happens during a mammogram? 

  • You will need to undress from the waist up.

  • The technologist will position your breast to get the best test results.

  • Each of your breasts will be compressed one at a time. This helps get the most complete X-ray image.

  • Your breasts will be repositioned to get at least 2 separate views of each breast.

What happens after a mammogram?

  • More X-rays are sometimes needed. You’ll be called to schedule them.

  • You should receive your test results in writing. Ask about this on the day of your appointment.

  • Have mammograms as often as your healthcare provider recommends.

Let the technologist know if:

  • You’re pregnant or think you may be pregnant

  • You have breast implants

  • You have any scars or moles on or near your breasts

  • You’ve had a breast biopsy or surgery

  • You’re breastfeeding
