Doctors and scientists agree that early detection is the best defense against breast cancer. If we find cancer in its earliest stage, the chances of surviving it are good. Until now the best way to do that has been with digital mammography.
While digital mammography is still one of the most advanced technologies available, it is only a 2-Dimensional image of the breast.
Scientists have developed a new technology called Breast Tomosynthesis, which has been shown in clinical studies to be superior to digital mammography. Breast tomosynthesis allows doctors to examine breast tissue one layer at a time
Breast tomosynthesis may be used in conjunction with traditional digital mammography as part of your annual screening mammogram to capture more breast images.
During tomosynthesis images of the breast are taken and then high-powered computing is used to convert digital breast images into a stack of very thin layers or “slices” building a 3-Dimensional mammogram.
Using 3D mammography and digital mammography together for screening has been proven to significantly reduce “call backs” by 20-40%. In addition, 3D mammography finds cancers earlier than 2D mammography alone, with a 27% increase in cancer detection rate and a 40% increase in invasive cancer detection.
What to expect during your exam:
A 3D mammogram is very similar to a traditional mammogram. The technologist will position you, your breast will be placed in compression under a paddle. While in compression the digital mammogram and tomosynthesis images are obtained at the same time. The x-ray arm sweeps in an arch over the breast and multiple images will be taken in seconds. There is no additional compression required with 3D mammography, and it only takes a few seconds longer for each view.
