That results in lots of needless worry for women and their families — not to mention the time, discomfort and expense of additional tests, including ultrasounds and biopsies. Recently, a different type of test, ultrasound elastography, has been used to pinpoint possible tumors throughout the body, including in the breast. “It uses imaging to measure the stiffness of tissue, and cancer tissues are stiff,” says Jingfeng Jiang, a biomedical engineer at Michigan Technological University. Those images can be breathtakingly clear: Jiang shows one elastogram in which the tumor is as different from normal breast tissue as a yolk is from the white in a fried egg. …
