Screening blood test for ovarian cancer?

Currently, there is no reliable screening blood test for ovarian cancer that is recommended for the general population. The most commonly discussed test is the CA-125 blood test, which measures the level of a protein that may be elevated in women with ovarian cancer, but it is not specific enough to be used for screening. This test can lead to false positives and unnecessary procedures in women without cancer. Regular pelvic exams and awareness of symptoms are important for early detection, especially for women at high risk.
