Lung Cancer: Lung cancer is a disease of uncontrolled cell growth in tissues of the lung. A malignant tumor arising from the cells of the respiratory epithelium. By definition, tumors arising from non epithelial cells (sarcoma and lymphoma) or from mesothelial lining (mesothelioma) of the lung are excluded. This uncontrolled cell growth may lead to metastasis, invasion of adjacent tissue and infiltration beyond the lungs.
