What you need to know about 3-D mammography

You may have heard of 3-D mammography, but are unsure how it’s different than standard 2-D mammography. More importantly, you may be unsure if 3-D mammography is right for you. Here are five things you should know about 3-D mammography:

What is 3-D mammography? 

A three-dimensional (3-D) mammogram, also known as breast tomosynthesis, is the newest FDA-approved technology for breast imaging. It produces a 3-D picture of your breast by taking several X-rays from different angles. A computer turns these X-rays into 3-D images using technology similar to a CT scan.

What is the advantage of 3-D mammography?     

Research shows that for women with dense breast tissue or strong risk factors for developing breast cancer, 3-D mammography provides improved visualization and the following patient benefits compared to 2-D mammography:
  • Detects 41 percent more invasive breast cancers1
  • Detects cancers 15 months earlier2
  • Reduces false positive readings by up to 40 percent1

How do I know if I have dense breasts?

After your annual screening mammogram (using either 2-D or 3-D technology), your imaging provider will notify you by letter if you have dense breasts. At Palmetto Health Breast Center, we encourage patients who have dense breasts to talk with their physicians so they can make an informed decision about the need for 3-D mammography at their next annual screening mammogram.

Does a 3-D mammogram feel any different?

A 3-D mammogram will feel just like a 2-D mammogram. It requires the same number of X-rays and the same amount of compression as a 2-D mammogram.

Does insurance cover 3-D mammography?

Currently Medicare and some commercial insurance plans cover 3-D mammography. We encourage patients to contact your insurance plan before your next screening mammogram to learn about your plan benefits. 
 
All women should begin regular screening mammography at age 40, or younger if they have a family history of breast cancer. To learn more, visit PalmettoHealth.org/BreastCenter.
