A large study in the Journal of the American Medical Association finds adding 3-Dimensional imaging to standard digital mammography increases cancer detection. Researchers say the results could lead to changes in the way we screen for breast cancer.
A study of nearly half a million women finds screening with both 3-D imaging and digital mammography detects 41 percent more invasive cancers that just traditional mammography alone.
"If you think of a book, we are able to page through the breast with one millimeter slices and see inside the breast" says Dr. Sarah Friedewald
The closer look also results in 15 percent fewer unnecessary follow-up tests because of false alarms.
There is still controversy over whether early breast cancer detection leads to better outcomes. A MRI is still recommended for women at high risk of breast cancer .
