New blood test could improve outcomes for those at risk of ovarian cancer

California researchers are revealing a medical breakthrough that could improve the outcomes for those at risk of ovarian cancer. According to the CDC, ovarian cancer is the second most common form of gynecologic cancer in the U.S. and causes more deaths than any other cancer of the female reproductive system. KTVU's Heather Holmes speaks with Dr. Bodour Salhia of the USC Norris Comprehensive Cancer Center about the potential of a new blood test that could help detect ovarian cancer much earlier and for patients who haven't yet shown any symptoms.
