1 Numerous studies have shown that lung cancer is more likely to occur in both smoking and non-smoking relatives of those who have had lung cancer than in the general population. 2  Air pollution from vehicles, industry, and power plants, can raise the likelihood of developing lung cancer in exposed individuals.
The lungs are a pair of spongy, air-filled organs located on either side of the chest (thorax). The trachea (windpipe) conducts inhaled air into the lungs through its tubular branches, called bronchi. The bronchi then divide into smaller and smaller branches (bronchioles), finally becoming microscopic. Lung cancer: Cancer may affect almost any part of the lung. 2  Most lung cancer is caused by smoking. 3  Tuberculosis: A slowly progressive pneumonia caused by the bacteria Mycobacterium tuberculosis. 4  Chronic cough, fever, weight loss, and night sweats are common symptoms of tuberculosis.
