Disorder of lung
A non-neoplastic or neoplastic disorder affecting the lung. Representative examples of non-neoplastic disorders include chronic obstructive pulmonary disease and pneumonia. Representative examples of neoplastic disorders include benign processes (e.g., respiratory papilloma) and malignant processes (e.g., lung carcinoma and metastatic cancer to the lung). [from NCI]
Chronic obstructive pulmonary disease
Chronic obstructive pulmonary disease (COPD) is a common, complex disorder associated with substantial morbidity and mortality. COPD is defined by irreversible airflow obstruction due to chronic bronchitis, emphysema, and/or small airways disease. Airflow obstruction is typically determined by reductions in quantitative spirometric indices, including forced expiratory volume at 1 second (FEV1) and the ratio of FEV1 to forced vital capacity (FVC) (Silverman et al., 2002; Celedon et al., 2004).
