Imaging centers across the country are adding three-dimensional (3D) mammography to the traditional 2D offering for its proven ability to better detect cancers. But, what’s less understood is its accuracy in detecting more advanced forms of cancer.

A recent Kaiser Health News article reports these facilities are on the rise as there are now 3,915 certified mammography imaging facilities that offered 3D mammography, or digital breast tomosynthesis—an increase from 3,011 facilities the previous January.

While this new imaging modality has demonstrated enhanced capability in detecting cancers than 2D imaging, it is not yet known if this new technology can more accurately detect advanced cancers that will become deadly.

“Cancers don’t always progress and kill people,” said Etta Pisano, MD and chief science officer at the American College of Radiology’s Center for Research and Innovation and a faculty member at Harvard Medical School to KHN. Pisano is leading a five-year clinical trial of 165,000 women that will compare the two types of screening tests to evaluate whether the new technology reduces the risk that women will develop life-threatening cancers, according to the repot.

While 3D mammography’s advanced cancer detection is still unknown, what is clear is this new way of screening is more expensive than the traditional imaging, although some researchers believe the new 3D digital mammography may reduce cancer screening costs in the long run.
