An X-ray showing a tumor in the lung

Lung cancer is a disease of uncontrolled cell growth in tissues of the lung. It may metastasise beyond the lungs. Lung cancer is responsible for 1.3 million deaths worldwide annually and is the most common cause of cancer-related death in men and the second most common in women. The most common symptoms are shortness of breath, coughing, and weight loss. The main types of lung cancer are small cell lung carcinoma and non-small cell lung carcinoma. Treatment and prognosis depend upon the histological type of cancer, the degree of spread, and the patient's performance status. Treatments include surgery, chemotherapy, and radiotherapy. Non-small cell lung carcinoma may be treated with surgery, while small cell lung carcinoma usually responds better to chemotherapy. With treatment, the five-year survival rate is 14%. The most common cause of lung cancer is exposure to tobacco smoke. Genetic factors, radon gas, asbestos, and air pollution may also contribute. (Full article...)
