Non-small cell lung cancer has four main stages: Stage 1: Cancer is found in the lung, but it has not spread outside the lung. There are two main types of lung cancer: small cell and non-small cell. Declines in Diffusing Capacity are also associated with worse outcomes. Results are displayed as a volume of air as well as a percent predicted. Smoking does not increase th… When these particles are introduced into the respiratory tract, they can cause a reactive process in the lung tissue known as pneumoconiosis. Studies have confirmed that patients with fewer symptoms of shortness of breath generally have a better prognosis. Both are caused by exposure to coal dust.
