A new study found that adding a 3-dimensional breast imaging technique to digital mammography has improved cancer detection. Not only did it increase the cancer detection rate, but it also cut down on the number of women called back for additional imaging, resulting in the findings of more invasive cancers.
Researchers studied data from 13 breast imaging centers. In 2011, the FDA approved 3D imaging to be used in combination with standard digital mammography for breast cancer screening. Results showed a decrease in the number of callbacks, an increase in cancer detection in general, and an increase in more invasive cancers that were sent for biopsy.
Researchers say the success of mammography screening lies in detecting and treating small cancers, with no symptoms, before they spread. The results of this study were encouraging, but more studies are needed.
Complete findings for this study can be found in the Journal of the American Medical Association.
