"Italian scientists have developed and are testing a hand-held scanner, similar to metal detectors used in airports, to diagnose cancerous tumours. In clinical trials of the device called Trimprobe, the scanner pinpointed 93 percent of prostate cancer tumours that were later confirmed by biopsies. 'The development holds out the prospect of a mass-screening technology that is cheap, quick and non-invasive,' New Scientist magazine said on Wednesday," Reuters reports here. Sounds kinda fishy to me, but if it holds up, it's pretty cool news.
