What is the most common lung cancer among non smokers?
Adenocarcinoma, the most common lung cancer diagnosed in nonsmokers, often starts in the outer areas of the lungs, in mucus-producing cells that line the small airways, called bronchioles.

Cigarette smoking is the number one risk factor for lung cancer. In the United States, cigarette smoking is linked to about 80% to 90% of lung cancer deaths. Using other tobacco products such as cigars or pipes also increases the risk for lung cancer. Tobacco smoke is a toxic mix of more than 7,000 chemicals.
Is lung cancer rare in 30s?
Lung cancer is one of the most common cancers in the world. This disease occurs mostly in men over 50 years old, most often at the age of 60–75 years. It is diagnosed in young patients very rarely.
