A few years ago, the U.S. Food and Drug Administration approved the use of three-D mammography. And three-D technology found Jennifer Hoeft's tumor.

"It was a very small tumor. It was only an 8 millimeter tumor that couldn't be felt."

Sarah Friedewald is a doctor at Lutheran General Hospital in the U.S. state of Illinois. She led a study to compare the results of three-D and two-D mammography from nearly a half million patients.

Dr. Friedewald says they found more cancers using three-D mammograms versus, or compared to, two-D mammograms. And they found more cancers that kill.

"We found invasive cancers or the cancers that we worry about, the ones that could potentially kill people more frequently in women who had the 3-D mammogram versus the women who just had the 2-D mammogram."

The White House in Washington is bathed in pink light to celebrate Breast Cancer Awareness Month.

Dr. Friedewald says tumors that are difficult to see on a standard mammogram are easy to find in 3 dimensions.

Jennifer Hoeft is grateful that she had three-D mammography.

"I truly, truly believe that the 3-D mammography is what caught my cancer early and is allowing me to pretty much live my life the way I want to."
