MINNEAPOLIS (WCCO) — New technology could help women by detecting breast cancer earlier.

A new study shows that adding 3D technology to standard digital mammography leads to better screening. Researchers say the results could lead to changes in the way doctors screen for breast cancer.

A study of nearly half a million women found that screening with both 3D imaging and digital mammography detects 41 percent more invasive cancers.

That closer look also results in 15 percent fewer unnecessary follow-up tests because of false alarms.

“If you think of a book, we are able to page through the breast with one millimeter slices and see inside the breast,” said Dr. Sarah Friedewald of Advocate Lutheran General Hospital. “I expect 3D to largely replace the standard 2D over time as it becomes more accessible to patients.”

There is still some controversy over whether early breast cancer detection leads to better outcomes.

An MRI is still recommended for women at high risk of getting breast cancer.
