In brief: Several causes...

But the most common correlation with lung cancer is smoking.
Smoking alone will increase your risk of lung cancer by about 20 times by smoking one pack per day for twenty years. Other sources can be genetic (alpha-1 antitrypsin disorder), related to environmental exposures that are inhaled, or other less common reasons.

Second hand smoke and radon gas are also causative factors but not as strong as smoking. The other factor is genetic susceptibility.

Gl/gu9ms as noted by others, number one/major cause is exposure to inhaled carcinogens, particularly combustion/burning products (i.e. Tobacco, marijuana, etc...). Other inhalants are also noted risk factors. Be well and respect yourself.

In brief: Many things

>80% of lung cancer is caused by smoking.
However never smokers (defined as <100 cigarettes in lifetime) can get smoking. Risk factors include radon exposure, second hand smoke, and genetic mutations such as egfr activating mutations. For more info: http://bit.Ly/ygfoko.

In brief: Mainly smoking

But a lot of other factors (most of which can nit be altered) may play a role.
Over 85% of lung cancers are seen in smokers, so if you would like to decrease your chances of getting lung cancer (and also cardiovascular disease!) quit smoking now!
