Many people say that the cell phones causes cancer and some says it doesn't but one thing which the Researchers at Massachusetts General Hospital proved is that they can be used to detect tumors. At Boston have developed a system can detect tumors by analyzing a few thousands cells and spare patients from the larger biopsies currently used. It works by using magnetic nanoparticles to measure protein levels, looking for specific markers that indicate the presence of cancer. Doctors can see the information from the chip on their phone's screen.
To test this device the Researchers have conducted two tests in both of them they get quite good results even in the second test the accuracy is about 100%. The smart-phone-equipped device is also much faster than current methods, providing results in under an hour which is way faster than the usual three day wait.
According to the researchers this device isn't quite ready for clinical use. One problem is that the relevant protein markers aren't always present in cancer cells, which could lead to misdiagnoses. The proteins are also short-lived, meaning that cells should be analyzed soon after they are extracted.
