The National Cancer Institute and the American College of Radiology can both direct you to facilities that perform mammograms, notes BreastCancer.org. Make sure that any facility you choose has state-of-the-art equipment and is certified by the ACR.
Mammograms require X-rays, so they are typically done by diagnostic imaging facilities, explains BreastCancer.org. Since most of these facilities do a wide variety of imaging work, try to find one that does a substantial amount of mammograms to help ensure that they can interpret the results correctly. Ask each facility how many mammograms they perform each day, and select one that does at least 15. Ideally, look for a facility that has two radiologists review the films.
The United States Centers for Disease Control and Prevention and the United States Food and Drug Administration also provide search tools, as noted on their respective websites. These tools allow you to search for facilities by location and other factors.
If you need a low-cost mammogram, first make sure that your insurance does not cover it, suggests Susan G. Komen. That organization works with local providers to find low-cost providers, so contact its breast cancer helpline for assistance. The National Breast and Cervical Cancer Control Program also helps provide low-cost screening, and more information is available through the CDC website.
