  • From VOA Learning English, this is the Health Report.

  • Three-dimensional technology -- known as three-D -- gives depth to objects
  • 3
  • that would otherwise appear two-dimensional, or flat.
  • 4
  • Three-D makes movies and video games look more realistic.And now it could help save lives.
  • 5
  • For years, mammograms have played an important role in finding breast cancer.
  • 6
  • But these X-ray pictures of the human breast often miss dangerous lumps or tumors.
  • 7
  • And they also produce false positives.A false positive wrongly appears to show suspicious tissue.
  • 8
  • And that causes painful, unnecessary biopsies to examine that tissue.
  • 9
  • A new study shows that three-D technology could change the way doctors look for breast cancer.
  • 10
  • When Zulima Palacio discovered she had breast cancer, it already had reached stage three.
  • 11
  • That means that the cancer was very dangerous.
  • 12
  • "Even a month before it was detected,
  • 13
  • I went for a sonogram and they told me, 'You're fine, go home.'"
  • 14
  • Ms. Palacio is now cancer free.
  • 15
  • But the standard two-dimensional mammogram missed all three of her tumors.
  • 16
  • Many doctors - including cancer surgeon Negar Golesorkhi -
  • 17
  • say standard mammography does not find enough cancerous tumors.
  • 18
  • She says looking for cancer in dense, thick breast tissue is like looking for a polar bear in a snow storm.
  • 19
  • In other words, it is very difficult.
  • 20
  • "When we look for cancer on a mammogram in dense breast tissue,
  • 21
  • we're looking for a polar bear in a snow storm, so it would be very difficult to find."
  • 22
  • A few years ago, the U.S. Food and Drug Administration approved the use of three-D mammography.
  • 23
  • And three-D technology found Jennifer Hoeft's tumor.
  • 24
  • "It was a very small tumor. It was only an 8 millimeter tumor that couldn't be felt."
  • 25
  • Sarah Friedewald is a doctor at Lutheran General Hospital in the U.S. state of Illinois.
  • 26
  • She led a study to compare the results of three-D and two-D mammography from nearly a half million patients.
  • 27
  • Dr. Friedewald says they found more cancers using three-D mammograms versus,
  • 28
  • or compared to, two-D mammograms.
  • 29
  • And they found more cancers that kill.
  • 30
  • "We found invasive cancers or the cancers that we worry about,
  • 31
  • the ones that could potentially kill people more frequently in women
  • 32
  • who had the 3-D mammogram versus the women who just had the 2-D mammogram.
  • 33
  • At the same time, fewer people had to come back for unnecessary testing which creates unnecessary anxiety."
  • 34
  • Dr. Friedewald says tumors that are difficult to see on a standard mammogram are easy to find in 3 dimensions.
  • 35
  • Jennifer Hoeft is grateful that she had three-D mammography.
  • 36
  • "I truly, truly believe that the 3-D mammography is what caught my cancer early
  • 37
  • and is allowing me to pretty much live my life the way I want to."
  • 38
  • Dr. Friedewald told VOA that she expects three-D to replace the usual two-D mammograms in time.
  • 39
  • Her study was published in the Journal of the American Medical Association.
  • 40
  • And from VOA Learning English, that's the Health Report.
