Washington: Scientists have developed a new screening strategy for ovarian cancer that can accurately detect the disease before it becomes lethal.There currently are no established screening strategies for ovarian cancer. The disease often causes no specific symptoms and is difficult to detect in the early stages when it is most responsive to treatment.Therefore, ovarian cancer is highly lethal because most women have advanced disease when they are diagnosed.Karen Lu, of The University of Texas MD Anderson Cancer Center in Houston, led a team that tested the potential of a two-stage ovarian cancer screening strategy that incorporates changes in a blood protein called CA125, which is a known tumour marker.In their 11-year study, 4051 post- menopausal women initially underwent an annual CA125 blood test.
