One step closer to ovarian cancer marker, researchers report

The hunt is on to find biomarkers that detect cancer, but it's a challenging process. Early successes often are followed by heartbreaking failures. But now, researchers have verified that glycans (sugars attached to proteins) can be used to detect ovarian cancer. Creating a diagnostic tool that identifies ovarian cancer early through analysis of a blood sample would be an enormous benefit. Because the disease produces indistinct symptoms, such as bloating, ovarian cancer is often diagnosed late,...
