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. 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 very difficult. A few years ago, the U.S. Food and Drug Administration approved the use of three-D mammography. Three-D technology found Jennifer Hoeft’s tumor although it was only eight millimeters in size and could not 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 500,000 patients. Dr. Friedewald says they found more cancers using three-D mammograms. And they found more dangerous cancers. Dr. Friedewald says tumors that are difficult to see on a standard mammogram are easy to find in 3 dimensions. She expects three-D to replace the usual two-D mammograms in time.
