Researchers have developed a novel blood test called biomarker test that offers the possibility of more precise diagnostics of ovarian cancer without the need for surgery. Biomarker test is based on analysis of 11 proteins and is performed on a blood sample where ultrasound indicates abnormalities to identify women without cancer. As majority of women who undergo surgery for suspected ovarian cancer do not have cancer this research could lead to a reduction in unnecessary surgery and in earlier detection and treatment for affected women. Ovarian cancer is often discovered at a late stage and has a high mortality rate.
