The majority of lung cancers derived from cells in the lungs, but lung cancer can also originate from cancer in other body parts that spread to the lungs. 

Lung cancer is the most common cancer in both men and women. 

Lung cancer is also the leading cause of cancer deaths. 

More than 90% of lung cancers originated from the bronchi (large airways into the lungs), cancer is called carcinoma bronkogenik, which consists of: 

• small cell carcinoma or squamous cell wheat 

Alveolar cell carcinoma derived from air pockets (alveoli) in lungs. This cancer can be a single growth, but often strike more than one area in the lung. 

Lung tumors are less common are: 

• Sarcoma (malignant) 

Lymphoma is a cancer of the lymph system, which can be derived from the lung or is spread from other organs. 

Many cancers that originate from other places to spread to the lungs. 

Only a small proportion of lung cancers (about 10% -15% in men and 5% in women) caused by or inhaled substances encountered in the workplace. 

Working with asbestos, radiation, arsenic, chromate, nickel, chloromethyl ethers, mustard gas and coke oven emissions can cause lung cancer, although usually only occurs in workers who also smoke. 

Sometimes lung cancer (particularly adenocarcinoma and alveolar cell carcinoma) occurred in people who already have lung scarring due to other lung diseases, like tuberculosis and fibrosis.
