The U.S. Food and Drug Administration (FDA) is alerting patients who had mammograms at Coastal Diagnostic Center in Pismo Beach, California, on or after Feb. 24, 2013, about possible problems with the quality of their mammograms. This does not mean that the results of the mammograms were inaccurate, but it does mean that the patients should consider having their mammograms re-evaluated at a Mammography Quality Standards Act (MQSA)-certified facility to determine if they need a repeat mammogram or additional medical follow-up.
