Causes Of Lung Cancer

1. Smoking-related air pollution
   The most common cause of lung cancer in both smokers and nonsmokers is smoking-related air pollution. The leading cause of all lung cancers is smoking-related air pollution. There are about 600 different ingredients in tobacco. When smoked, they produce more than 7,500 different compounds that are suspected of causing cancer. Even more importantly, many of those compounds are toxic, so it’s no wonder that those who regularly smoke have a significantly higher risk of getting lung cancer as well.
