J&J and MGH Go After the Cancer Blood Test

January 4, 2011 | Johnson and Johnson and Massachusetts General Hospital are developing and marketing a blood test that could find a single cancer cell in a person's blood. Dr. Mehmet Toner, director of the BioMicroElectroMechanical Systems Resource Center in Massachusetts General's Center for Engineering in Medicine, says while it will take at least five years before the test is on the market, it's another step toward personalized medicine and the implications for patients are significant. "It is very big. It has the potential to turn cancer into a chronic disease, because we can monitor patients individually and respond with treatment to the genetic makeup of their cancer." CNN
