I was amazed to read Gina Kolata's NY Times article on CT scans and lung cancer screening. Why the surprise? It's very good. Sober, measured, informative. I'm not accustomed to good reporting on this type of story. Journlists matter, and Kolata is one of the very best writing on healthcare topics.
Oh, the conclusion? Looks interesting, probably insurers will pay, risk and benefit is not yet known, better studies will have results in 1-2 years. I'd say 65% probability this will turn out to be a weak screening test.
