Ovarian cancer is a silent killer that displays few obvious symptoms. But researchers from the Georgia Institute of Technology may have the answer for detecting the disease early. In a recent study, they detected ovarian cancer from blood samples with near 100 percent accuracy. "Because ovarian cancer is a disease of relatively low prevalence, it's essential that tests for it be extremely accurate. We believe we may have developed such a test," says John McDonald, chief research scientist at the Ovarian Cancer Institute. Report
