cancer, the deadliest form of cancer in the United States. But doctors have to consider the potential harm of radiation exposure when ordering screening. The initial 2010 trial suggested that the low dose CT scans can save lives, but they're not yet routine and insurers typically don't pay for them.
After follow up, lung cancer was diagnosed in 1.1 percent of the patients in the CT group and 0.7 percent of the X ray group, the researchers reported in the May 23 issue of the New England Journal of Medicine.

and former heavy smokers, aged 55 to 74, who underwent a CT scan or chest X ray every year for three years, starting in 2002.
CT Scans Reduce Lung Cancer Deaths
The CT scans were much more likely to pick up lung cancer in its early, more treatable stages: stage 1 cancer was found in 158 CT scan patients versus 70 X ray patients, according to the study.
CT scans revealed potential signs of cancer in 27 percent of those scanned, compared to 9 percent of people who got X rays, the researchers found. In both groups, about 91 percent had at least one more test.
By 2010, the death rate among those who got the CT scans was 20 percent lower than for those who got X rays.

About 158,000 people die from lung cancer in the United States each year, often because it's detected too late for effective treatment. The new analysis of the 2010 study indicated that by identifying malignancies sooner, low dose CT scans will reduce the death tally.
