Lung Cancer Screening Encouraged for Smokers
Lung Cancer Screening
To detect invasive lung cancer in its early stages, researchers urge current and former smokers who have a strong family history of the disease to take a lung function test and undergo screening with spiral computed tomography. The test is especially important should the previously diagnosed relative be young (around 50).
These findings appear in an article on familial lung cancer in the first issue for January 2006 of the American Journal of Respiratory and Critical Care Medicine, published by the American Thoracic Society.
(The screening test, spiral computed tomography, uses a 360-degree X-ray beam, along with computer production of image "slices," to highlight lesions in organs and tissues.)
Ann G. Schwartz, Ph.D., of the Karmanos Cancer Institute in Detroit, Michigan, along with an associate, emphasized that 85 to 95 percent of all lung cancers are attributable to cigarette smoking.
