3-D Mammography: Frequently Asked Questions
Who should choose a 3-D mammogram?
While all women can benefit from a 3-D exam, it is particularly beneficial if you have dense breast tissue or a family history of breast cancer.
Finding breast cancer early could save your life — 98 percent of women survive breast cancer when it is found in its earliest stage.
What is the difference between traditional 2-D and the new 3-D mammograms?
Two-dimensional imaging provides two flat images of the breast—one from the top of the breast and one from the side. Three-dimensional imaging provides images of the breast in slices, which allows radiologists to examine the breast tissue layer by layer. This makes it possible for doctors to see abnormalities that were hidden by overlapping tissue on 2-D mammograms.
Three-dimensional mammograms also reduce the chances of getting called back for more screenings.
Is there more radiation in a 3-D versus 2-D exam?
Adding 3-D to a traditional 2-D exam increases the radiation dose somewhat, but the combination is still well below federal limits on radiation exposure. In fact, the combination emits less radiation than the amount an average person receives annually from the environment. Because 3D imaging will reduce the number of callbacks for additional screening, you could actually have reduced radiation exposure by avoiding the need for additional mammogram views.
Is the actual exam for a 3-D mammogram any different than that of a 2-D?
You will notice no difference in a 3-D mammogram versus 2-D mammogram. Compression is the same in each exam and it only takes a few seconds longer for each view. Three-dimensional imaging supplements the traditional 2-D image and is performed at the same time with the same system.
