Soon, a bra, universally used to provide support and comfort to the breasts, might offer health benefits, for scientists at the University of Bolton are developing a bra that can detect if the person wearing it is suffering from early-stage breast cancer. Professor Elias Siores, inventor of the bra, who works in the Centre for Research and Innovation at the University of Bolton, also claims that the undergarment will be able to assess the effectiveness of any breast cancer treatment its wearer is undergoing. The smart bra works by using a microwave antennae system, which can easily be woven into fabric. The antennae pick up any abnormal temperature changes in the breast tissue, which are linked to breast cancer cells. Siores said that an efficient way to use the bra would be to wear it while plugged into a power supply for a few minutes during diagnosis. The lifesaving undergarment will be manufactured within the next two years A.can offer stronger support and comfort to the breasts than traditional ones.
