What is the latest technology in mammograms?

Tomosynthesis, also known as 3-D mammography, allows the breast to be viewed in 1-millimeter, 3-D “slices,” as opposed to the current standard of 2-D mammography. This new technology increases the specificity and sensitivity of mammograms; it’s been shown in studies to increase cancer detection.

Is there a less painful mammogram?

A French study suggests that mammograms are just as effective and cause less discomfort when women can control the amount of compression. The study was published online on Feb. 4, 2019, by the journal JAMA Internal Medicine.

When is a breast biopsy necessary?
