Researchers Tackle Ovarian Cancer Using a Multidisciplinary Approach

September 11, 2017

September is National Ovarian Cancer Awareness Month. Ovarian cancer is among the most deadly of all cancers, though because of less awareness, most cities won’t be as blanketed in teal (ovarian cancer’s awareness color) as they are bathed in pink for October’s focus on breast cancer. But researchers at the Harper Cancer Research Institute, a collaboration between the University of Notre Dame and the Indiana University School of Medicine South Bend, are working with community partners to not only foster awareness of ovarian cancer but also to develop tests for early detection, create novel chemotherapies, and target a cure.
