New test could save lives from ovarian cancer
While ovarian cancer is treatable if it is detected early, but 70 percent of cases are not diagnosed until it is too late.
Ovarian cancer is often deadly because it has few, if any, symptoms and there is no screening test.
However, a promising blood test may change that.
For 11 years, scientists at M.D. Anderson Cancer Center had 4,000 post-menopausal women undergo a blood test that looks for CA-125, a known ovarian tumor marker.
They found the test had a low false positive rate and, of the seven women whose cancers were diagnosed as a result of the test, all of their cancers were detected at an early stage.
If those results are confirmed in clinical trials, the test could become a routine screening for women.
