Respiratory Diseases

As a respiratory disease, lung cancer has now become the leading cause of death from cancer in men. It accounts for the second largest number of cancer deaths in women. Cigarette smoking and air pollution are considered to be the two main causes of lung cancer. The three types of lung cancer are carcinomas, lymphomas, and sarcomas. The survival rate after five years for carcinomas, which can originate in the trachea, bronchi, or alveoli, is low. Lymphomas originate in the lymph nodes, while sarcomas develop either in the lungs or in other body tissues. Treatment includes the use of chemotherapy, radiation, and surgery, that is, the removal of the affected parts of the lung.
