Survival vs. mortality results from cancer detection

Many new medical interventions look good when evaluated by survival time but fail when
evaluated by mortality rates. See a fine article in The New York Times

here, an article that would appear in no other newspaper.

Alvin
Feinstein, my colleague at Yale, made the point for years that early diagnosis makes
treatments look good because early diagnosis leads to longer survival times–but often with
no improvement in mortality rates.
