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.
A woman undergoes a mammography exam, a special type of X-ray of the breasts used to detect tumors.
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.'"
Ms. Palacio is now cancer free. But the standard two-dimensional mammogram missed all three of her tumors.
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 a 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 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."

这里是美国之音慢速英语健康报道。
三维技术(3D)使得原本以二维表现的平面物体有了厚度，3D使得电影和视频游戏看起来更真实，现在3D可以用来拯救生命。
多年来，乳房X光检查在发现乳癌方面发挥了重大作用，但人类乳房的X光照片通常会忽略掉肿块或肿瘤。
同时还会造成误报，误报会错误地显示可疑组织，这就导致痛苦、不必要的切片检查来复查这些组织。
最新研究显示，3D技术可以改变医生发现乳癌的方法。
当珠丽玛·帕拉西奥发现自己患有乳癌时，病情已经进入第三阶段，这意味着非常危险了。
“甚至在乳癌发现的一个月前，我去做乳房X光检查时他们还告诉我，‘没事的，回家吧。’”
帕拉西奥现在已经没有癌症了，但标准的二维乳房X光检查未能发现她的全部三个肿瘤。
包括肿瘤外科医生内加尔·格雷索克希在内的很多医生都说，标准乳房X光检查不能充分地发现危险的癌症肿瘤。她说在乳房密致组织中寻找癌症，就像在暴风雪中寻找白熊，也就是说非常困难。
“当我们用乳房X光检查在乳房密致组织中寻找癌症时，就像在暴风雪中寻找白熊，所以非常难以寻找。”
几年前，美国食品与药品管理局批准使用3D乳房X光检查，3D技术帮助发现了珍妮弗·赫夫特的肿瘤。
“这是个非常小的肿瘤，只有8毫米大，很难感觉到。”
莎拉·弗里德瓦尔德是美国伊利诺伊州路德总医院的一位医生，她负责领导了一项研究，从近50万患者中对比3D和2D乳房X光检查的结果。
弗里德瓦尔德说，与二维检查相比，3D乳房X光检查能找到更多癌症，还发现更多致命癌症。
“与那些只做了二维检查的妇女相比，我们在做了3D检查的妇女身上发现更多侵入性癌症或令我们担心的癌症，这些癌症可能会致命。”
弗里德瓦尔德说，在标准乳房X光检查中难以发现的肿瘤可以轻易在3D检查中发现。
赫夫特庆幸自己做了3D检查。
“我真的相信3D检查能提前发现我的癌症，让我能过上自己想要的生活。”
