Ian Lamont writes: "Researchers at Stanford say they have developed a blood scanner that can search for cancer-associated proteins in a blood sample and returns results in less than an hour. The device looks in a blood sample for cancerous proteins, and attempts to match them up with complementary proteins using chips based on magnetic nanotechnology. One of the researchers says the device could potentially help doctors identify lung cancer, ovarian cancer and pancreatic cancer at an early stage. The device still has to undergo clinical testing and trials before it can win regulatory approval."
