Despite advances in gynecologic oncology, ovarian cancer is still mostly diagnosed very late or in advanced stages, which leads to adverse outcome of the disease. The pathogenesis of this disease as well as the risk factors for its development are not completely understood, while symptoms in the early stage of disease are sometimes nonspecific and delay earlier diagnosis. The aim is to present recent knowledge about the screening and diagnosis of ovarian cancer, with sp6cial reference to the role of ultrasound in recognizing the disease and referring patients for further consultation.
