A new portable scanner for detecting early signs of breast cancer has been developed at the University of Manchester by Professor Zhipeng Wu. The device works by radio frequency technology that can show the presence of tumors on a computer screen. The amazing thing is that it can show the image within seconds on the computer screen, rather than an x-ray mammography which takes minutes and can only be done at hospital or specialist care centers. This new technology can revolutionize the early detection for women with breast cancer.
