Ovarian cancer is the main cause of death from gynaecological malignancies in the western world. The aim of the study is to develop a non-invasive diagnostic test for pre-symptomatic diagnosis of ovarian cancer. Early detection would have a profound effect on survival, which enables curative treatment for these patients. Achieving primary remedies (after surgery only) would greatly minimize the use of cytostatic drugs, which limits side effects and also reduces healthcare costs.
