Although the study finds the CA-125 blood test useful for evaluating treatment progress, the study results do not suggest the test can be used to screen
for ovarian cancer. A recent email making the rounds urged women to ask their doctors
for this test. For the CA-125 test to be a useful screening tool, it would have to detect most ovarian cancers in their early stages and not give positive results in women who do not have the cancer. The CA- 125 test does not meet these standards.
