So First Warning Systems, a company founded in Reno, Nev., in 2008, is designing and testing a smart bra that is essentially a continuous exam, and that thus far appears to be more accurate that the somewhat controversial mammography.

That sensor, meanwhile, communicates with pattern recognition software to help spot possible tumors long before a hand or mammogram likely would.… Read more
