Lungs are the organs that participate in gas transfer.

Passive smoking or any other exposure to cigarette smoke increases the risk of lung cancer among many other ailments. Smoking can cause damages to the fragile lining of the lungs, which is designed for air exchange, and when they are exposed to inhaled smoke and other carcinogens, the cells tend to change their nature in order to withstand these new stressors. As chronic exposure occurs, the cells mutate into cancerous cells. Inhaling carcinogenic substances such as asbestos, some types of coal dust and other chemicals too can increase the risk of getting lung cancer.

Other symptoms such as coughing up blood, Chest pain, Shortness of breath, and weight loss. It is important to diagnose Lung cancer at its early stages, as lung cancer can spread to other organs.
