3D mammograms create three-dimensional breast images
3D mammograms, also called breast tomosynthesis or tomo, is a newer technology. While taking X-ray images from the top and the sides, the machine moves in an arc motion (like a rainbow) over your breast to take multiple images of your breast tissue layers. The images are then digitally layered over each other to create a detailed three-dimensional image of your breast, which can provide additional information to your doctor.
When a 2D vs. 3D mammogram may be recommended for breast cancer screenings
2D mammograms have been the standard breast cancer screening method for many years. Generally, 2D is considered sufficient for those of average risk for breast cancer. But 3D mammograms are often recommended for those who have dense breast tissue or other risk factors for developing breast cancer.
