Magda El-Shenawee, a University of Arkansas engineer, thinks radar can be used to spot cancer buried in breast tissue.  Current mammograms make 2-D pictures by shooting x-rays through a breast squished between two plates.  They can save your life, but it's definitely not comfortable.  So El-Shanawee and others are developing small portable radar systems that would send harmless electromagnetic waves through a naturally-shaped breast.  She says a suspicious lump would scatter the waves in a way that engineers can turn into a precise 3-D image.  With the National Academy of Engineering, Randy Atkins, WTOP Radio.
