[ti:3-D Technology Saves Lives] [ar:Anna Matteo] [al:Health Report] [by:www.51voa.com] [00:00.00]From VOA Learning English, [00:02.35]this is the Health Report. [00:04.86]Three-dimensional technology -- known as three-D [00:09.78]-- gives depth to objects that would otherwise [00:14.19]appear two-dimensional, or flat. [00:18.14]Three-D makes movies and video games look more realistic. [00:24.80]And now it could help save lives. [00:28.44]For years, mammograms have played an important role [00:32.79]in finding breast cancer. [00:35.37]But these X-ray pictures of the human breast [00:38.93]often miss dangerous lumps or tumors. [00:43.85]And they also produce false positives. [00:47.86]A false positive wrongly appears to show suspicious tissue. [00:53.59]And that causes painful, [00:56.57]unnecessary biopsies to examine that tissue. [01:00.83]A new study shows that three-D technology [01:04.81]could change the way doctors look for breast cancer. [01:09.40]When Zulima Palacio discovered she had breast cancer, [01:14.32]it already had reached stage three. [01:18.41]That means that the cancer was very dangerous. [01:23.18]"Even a month before it was detected, [01:26.43]I went for a sonogram and they told me, [01:30.11]'You're fine, go home.'" [01:31.78]Ms. Palacio is now cancer free. [01:35.38]But the standard two-dimensional mammogram [01:38.96]missed all three of her tumors. [01:42.77]Many doctors - including cancer surgeon Negar Golesorkhi [01:48.60]- say standard mammography does not find enough cancerous tumors. [01:55.05]She says looking for cancer in dense, [01:59.35]thick breast tissue is like looking for a polar bear in a snow storm. [02:05.44]In other words, it is very difficult. [02:08.78]"When we look for cancer on a mammogram in a dense breast tissue, [02:15.01]we're looking for a polar bear in a snow storm, [02:18.76]so it would be very difficult to find." [02:20.85]A few years ago, the U.S. Food and Drug Administration [02:25.44]approved the use of three-D mammography. [02:29.41]And three-D technology found Jennifer Hoeft's tumor. [02:34.12]"It was a very small tumor. [02:35.48]It was only an 8 millimeter tumor that couldn't be felt." [02:38.68]Sarah Friedewald is a doctor at Lutheran General Hospital [02:43.98]in the U.S. state of Illinois. [02:46.73]She led a study to compare the results of three-D [02:51.50]and two-D mammography from nearly a half million patients. [02:56.98]Dr. Friedewald says they found more cancers [03:01.33]using three-D mammograms versus, or compared to, two-D mammograms. [03:08.94]And they found more cancers that kill. [03:13.50]"We found invasive cancers or the cancers that we worry about, [03:17.51]the ones that could potentially kill people more frequently [03:19.73]in women who had the 3-D mammogram [03:21.87]versus the women who just had the 2-D mammogram." [03:24.50]Dr. Friedewald says tumors that are difficult to see [03:28.86]on a standard mammogram are easy to find in 3 dimensions. [03:34.24]Jennifer Hoeft is grateful that she had three-D mammography. [03:40.16]"I truly, truly believe that the 3-D mammography [03:44.38]is what caught my cancer early and is allowing me [03:48.08]to pretty much live my life the way I want to."
