Can tumor markers be used as a screening test for cancer?
Screening tests are a way of detecting cancer early, before there are any symptoms. For a screening test to be helpful, it should have high sensitivity and specificity. Sensitivity refers to the test’s ability to identify people who have the disease. Specificity refers to the test’s ability to identify people who do not have the disease. Most tumor markers are not sensitive or specific enough to be used for cancer screening.

I would say that Recaf has a pretty great Sensitivity and Specificity.
