Scientists next asked if a new bioinformatics-based screening tool for ovarian cancer could be created using low-molecular-weight proteins in blood serum as the biomarkers. Could this tool accurately handle specimens of unknown cancer status? If so, researchers could devise a minimally invasive test for the detection of early-stage ovarian cancer. If so, their bioinformatics-based technology might also have broad application to the early diagnosis of many other cancers as well.
