Non-small cell lung cancer (NSCLC) usually takes years
to develop. Patients at an early stage usually do not have any symptoms
and abnormalities cannot easily be detected through X-Ray. Usually
NSCLC starts in the lining of the bronchi tubes leading into the lungs
but as the cancer develops, tumors can metastasize elsewhere.
NSCLC accounts for approximately 85% of lung cancers
with three sub-types: adenocarcinoma is the most common type of cell
type followed by squamous cell carcinoma and large-cell undifferentiated
carcinoma.

Thoracic Society (ATS) Posts New Guidelines
for Diagnosing Asbestosis (9/22/04)
The American
Thoracic Society (ATS) updated the 1986 criteria for diagnosing and treating
patients with nonmalignant disease related to asbestos, according to a
report in the Sept. 15 issue of the American Journal of Respiratory and
Critical Care Medicine. These conditions include asbestosis, pleural
thickening or asbestos-related pleural fibrosis (plaques or diffuse
fibrosis), "benign" (nonmalignant) pleural effusion, and airflow
obstruction.
