Digital mammography may be more cost effective than film mammography when used on women who are under age 50, premenopausal or who have dense breasts.
The research findings in Tuesday's edition of the Annals of Internal Medicine follow a study of data collected through the Digital Mammography Imaging Screening Trial, a massive American College of Radiology Imaging Network effort that enrolled more than 49,500 women in the United States and Canada.
The initial article on the data, published in November 2005 by the New England Journal of Medicine, suggested that digital mammography is more accurate as a cancer screening tool in younger, premenopausal woman who have dense breasts.
Now, it appears that more expensive digital mammograms may be warranted only for women in this subset.
