3-D Technology Saves Lives
3-D Technology Saves Lives
From VOA Learning English, this is the Health Report.
Three-dimensional technology -- known as three-D -- gives depth to objects that would otherwise appear
two-dimensional, or flat. Three-D makes movies and video games look more realistic. And now it could help save
lives.
For years, mammograms have played an important role in finding breast cancer. But these X-ray pictures of the
human breast often miss dangerous lumps or tumors.
And they also produce false positives. A false positive wrongly
appears to show suspicious tissue. And that causes painful,
unnecessary biopsies to examine that tissue.
A new study shows that three-D technology could change the way
doctors look for breast cancer.
When Zulima Palacio discovered she had breast cancer, it already
had reached stage three. That means that the cancer was very
dangerous.
"Even a month before it was detected, I went for a sonogram and
they told me, 'You're fine, go home.'"
It is difficult to see tumors in dense

mammogram missed all three of her tumors.
mammography.
Many doctors - including cancer surgeon Negar Golesorkhi - say
standard mammography does not find enough cancerous tumors.
She says looking for cancer in dense, thick breast tissue is like looking for a polar bear in a snow storm. In other
words, it is very difficult.
"When we look for cancer on a mammogram in dense breast tissue, we're looking for a polar bear in a snow storm, so
it would be very difficult to find."
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 mammog...

“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. At the
same time, fewer people had to come back for unnecessary testing which creates unnecessary anxiety.”
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.”
Dr. Friedewald told VOA that she expects three-D to replace the
usual two-D mammograms in time. Her study was published in the
Journal of the American Medical Association.
And from VOA Learning English, that’s the Health Report.
