U.S. agency gives approval to first 3-D mammogram AFP February 12, 2011 The
first three-dimensional mammogram device was approved yesterday by the U.S.
Food and Drug Administration, in the hopes that the new technology would
improve early breast cancer detection. 
Currently the only technology on the market produces
two-dimensionalX-rayimagesof thebreast. 
"Physicians can now access this unique and innovative 3-D technology that
could significantly enhance existing diagnosis and treatment approaches,"
said Jeffrey Shuren, director of the FDA's Centre for Devices and
Radiological Health. 
A pair of studies reviewed by the FDA showed a seven-per-cent improvement in
the ability of radiologists to "distinguish between cancerous and
non-cancerous cases as compared to viewing 2-D images alone," the regulatory
agency said. 
The new device, called the Selenia Dimensions System, is made by the
Massachusetts-based company Hologic and functions as an upgrade to its
current 2-D FDA-approved system. 
The Canadian Cancer Society recommends women 50 to 70 years old have a
mammogram every two years and that women 40 to 50 ask their doctor about its
benefits and risks.
