New screening guideline for the deadliest form of cancer?

Researchers in New York report that millions of lives could be saved by detecting lung cancer early with annual CT scans and treating it immediately, when it can still be cured.

That line came from the NY Times article "Study Sees Gain on Lung Cancer," and is about the results from a study that was published in the NEJM. And as the article explains, there are many problems with the idea of having people go through regular CT scans of the chest (to look for lung cancer), similar to regular mammograms (for breast cancer), colonscopies (colon cancer), and pap smears (cervical cancer, which may be a thing of the past because of the new anti-HPV vaccine).
