Israeli scientists have developed a new radiation-free scanner that can detect breast cancer more effectively than traditional X-ray mammograms. The machine detects tumours using infrared beams and thermal energy, reports The Times of India. In a trial of 2,500 women, the scanner was found to be 92% effective in detecting breast cancer, compared to 80% for X-ray mammograms. It was also found to be better in identifying cancers in younger women. The device is expected to receive EU approval in 2012.
