Emphysema is destruction of lung parenchyma leading to loss of elastic recoil and loss of alveolar septa and radial airway traction, which increases the tendency for airway collapse. Lung hyperinflation, airflow limitation, and air trapping follow. Airspaces enlarge and may eventually develop bullae. Symptoms of emphysema: * Shortness of breath * Chronic cough with or without sputum production * Wheezing * Decreased ability to exercise Additional symptoms that may be associated with this disease include the following: * Anxiety * Unintentional weight loss * Ankle, feet, and leg swelling * Fatigue Possible Complications of Emphysema: * Recurrent respiratory infections * Pulmonary hypertension * Cor pulmonale (enlargement and strain on the right side of the heart) * Erythrocytosis (increased red blood cell count) * Death Lung carcinoma is the leading cause of cancer-related death worldwide. About 85% of cases are related to cigarette smoking. Symptoms can include cough, chest discomfort
