But the tests are not binary sick or healty. If your test gets more sensitive, then you have to shift the, say, PSA value that you use for a diagnosis. I really hope that false positives become a regular thing. For one it shows that the tests are working according to statistics. Second, getting comfortable with false positives means that you can more easily hold off treatment, if in your specific scenario the treatment is not beneficial - think an old test that doesn't find the cancer plus a new test that does; and the new test is shown to lead to overtreatment. We need to learn when to hold on and not to treat. And third, if testing for 10 things will find something that you don't want to know and harm your psyche, when you test for 100 things you will have almost certainty that there is a false positive and this can give you back some of the "blissfull ignorance" I believe (while the doctor can still give you the statistically best treatment).
