One of the most common questions we hear in our office is: Should I get a standard or a 3D mammogram? It’s an important question, and the answer could make a big difference in early breast cancer detection.
A Quick Look at Mammogram History
Mammograms have come a long way since 1913, when German surgeon Albert Salomon first used X-rays to examine breast tissue. The technology didn’t gain widespread acceptance until 1965 when French physicist Charles Gross developed the first dedicated breast imaging unit. By 1976, the American Cancer Society officially recommended mammograms for breast cancer screening, and in 2000, digital mammography became available.
The biggest breakthrough came in 2011 with the approval of 3D mammography (digital breast tomosynthesis)—a technology that is now the standard of care. Studies show that 3D mammograms detect 41% more invasive breast cancers than traditional 2D mammograms.
How Does a 3D Mammogram Differ from a Standard Mammogram?
A standard (2D) mammogram captures two flat images of the breast, which can sometimes make it difficult to see abnormalities—especially in women with dense breast tissue.
A 3D mammogram, on the other hand, takes multiple images from different angles, creating a more detailed, layered view of the breast. This makes it easier to detect cancer that might otherwise be hidden by overlapping dense tissue.
Why Is This Important for Women with Dense Breasts?
Breasts are made up of two types of tissue:
✔ Fatty tissue, which appears transparent on a mammogram, making it easier to see any concerns.
✔ Dense tissue, which appears solid white—just like breast cancer—making it harder to detect abnormalities.
Since younger women and many women over 40 have dense breast tissue, a 3D mammogram provides a clearer, more accurate picture, improving cancer detection and reducing unnecessary callbacks for additional imaging.
So, Should You Get a 3D Mammogram?
For most women, the answer is yes. The ability to detect more cancers while reducing false alarms makes 3D mammography a valuable tool in breast cancer screening. If you have dense breasts or want the most advanced screening technology available, a 3D mammogram is a smart choice.
