Smoking

Smokers who avoid inhaling may decrease their risk slightly, but are still exposed to lip, mouth and tongue cancer

Smoking is currently the Number One cause for Lung Cancer throughout the world. This then makes it also the easiest cause that can be prevented.

Smoking is defined by Wikipedia as the "inhalation of smoke from one end of the cigarette".
A cigarette is manufactured out of finely cut and cured tobacco leaves.
Cigarette smoke contains many chemicals destructive to the organs in our body.
These chemicals are also known carcinogens but there are some unknown chemicals which might cause some damage to the body.

Therefore, smoking has been linked to incidences of lung cancer throughout the world (through the use of observational studies). Wikipedia claims that "smoking men are 22 times more likely to die from lung cancer than non-smoking men and smoking women are 12 times more likely to die from lung cancer than non-smoking women." This shocking discovery has actually heightened the awareness that smoking is harmful to the body, but due to aggressive marketing by tobacco companies and the influence of the media, tobacco is still going strong.
