Sorry to hear about your mom. Ovarian cancer is one of the worst because it usually has no symptoms until it is very advanced. For any cancer, early detection is the key. That's when surgery, chemo and radiation are most likely to be most effective. So I think this is where these blood tests will have the largest impact.

Any cancer large enough to shed detectable amounts of DNA into the blood stream is quite a ways along. You want to detect the pre-malignant when it's a few millimeters in size. Which is hard enough on your skin, let alone an internal organ.
