Test may help identify lung cancer at early stage.
Byline: Judy Peres
CHICAGO _ Scientists may be close to being able to predict who will develop lung cancer _ a development that could prevent tens of thousands of deaths a year in the U.S. alone.
Using a molecular test called a microarray, a research team from Boston University has come up with an 80-gene "signature" that can identify lung cancer at a very early stage in smokers. More importantly, the team showed that it is possible to detect pre-cancerous changes in normal tissue.
"It's like a molecular Pap smear," said Dr. Avrum Spira, who led the investigation.
The Pap test, which can detect abnormal cells in cervical tissue, is credited with greatly reducing deaths from cervical…
