SAN DIEGO --
Researchers said damage to cells lining the mouth can predict similar damage in the lungs that can lead to lung cancer in smokers.Scientists studied lung and mouth samples from 125 longtime smokers and found specific damage to certain genes in 95 percent of those smokers.
Researchers hope to be able to swab the mouths of smokers some day and predict those who are developing lung cancer to save the person from a lung biopsy.
The process may lead to tests to predict other cancers.
The study was reported at a meeting of the American Association for Cancer Research in San Diego Sunday.
