11/07/05  Heavy smokers screened with low-dose CT scans reduce mortality rate by 20 percent.

A new study revealed that heavy smokers screened with low-dose CT scans reduce mortality rate by 20 percent compared to those screened using chest X-rays.

Screening using low-dose celical computed tomography can reduce lung cancer mortality by identifying tumors early. Scientists compared mortality rates between patients who received three annual screenings using low-dose CT scans compared to those receiving chest X-rays.

The study suggested that lung cancer mortality in heavy smokers can be reduced via screening. Screening s impact should not be considered alone, but rather in tandem with diagnosis.

In United States 94 million current or former smokers are at elevated risk of lung cancer.
