Should patients be allowed to self-refer for cancer tests?


I've always been a little nervous about 5 year survival as a measure. To reduce to the absurd, let us assume that current diagnostic methods result in all patients living 4 years and 364 days after diagnosis, 5 year survival 0%. If we can make the diagnosis 2 days earlier, 5 year survival becomes 100% but nobody has actually lived any longer at all. How much of any supposed increase in 5 year survival in any campaign to improve diagnostics is actually due to real improved survival and how much is due to apparent improved survival?
