Lung cancer is a type of cancer that forms inside your lungs. Like all organs, your lungs are made of cells. Sometimes something goes wrong with the cells and they multiply uncontrollably. This is called cancer.

Lung cancer is one of the most common forms of cancer in New Zealand. About 2,000 New Zealanders are diagnosed with lung cancer each year.

By far the most lung cancer cases are caused by cigarette smoking. The best way to reduce the number of people getting lung cancer is to reduce the number of people who smoke.
