How to tell one brain tumor from another

With more than 36,000 people being diagnosed with brain tumors each year, and another 150,000 patients suffering from the spread of other cancers to the brain, bioengineers are working hard to discover new ways to identify tumors more accurately so that better information can be made available to patients and their families and so that the very best treatment can be selected by doctors.

The brain tumor biochip may be just the breakthrough that's needed. This technology, being developed and tested by Tony Guiseppi-Elie and others at Virginia Commonwealth University's Center for Bioelectronics, Biosensors and Biochips, is intended to provide a detailed genetic fingerprint of each tumor, which doctors could then use to prescribe the most effective therapies available.
