(ANNOUNCER OPEN):
The National Cancer Institute is conducting a study to determine if screening people with either chest X-ray or spiral computerized tomography--also called spiral CT--before they have symptoms can reduce deaths from lung cancer. Doctor Denise Aberle--the principal investigator for the National Lung Screening Trial, or NLST--explains...

(ABERLE):
"Both chest X-rays and spiral CT scans have been used to find lung cancer early. But, so far, neither has been shown to be effective in reducing a person's chance of dying from lung cancer. So, this study is trying to find which of those two methods will be better at lowering lung cancer deaths. Now, the reason why that's important is because lung cancer itself accounts for about 28 percent of all cancer deaths in the United States."
