What are the possible causes of lung cancer besides smoking?

If you are a non-smoker and standing near a person smoking a cigarette, you should move away from that person as far as possible. It is because inhaling tobacco-infused smoke from other people’s cigarettes can damage the lungs and cause cancer. 

The U.S. Centers for Disease Control and Prevention (CDC) website has shown that radon, asbestos, arsenic, diesel exhaust, silica and chromium are risk factors for lung cancer. People living in big cities or have workplaces in areas that increase the risk of exposure are mostly affected by these chemicals.

Besides this, heredity is another major reason for lung cancer. People who have a family history of lung cancer in their first-degree relatives are at 50% higher risk of lung cancer than those with no family history of lung cancer. Another factor is people with cancer undergoing radiation therapy near the chest are often at a higher risk of cancer.

As cancer is now a lifestyle-related disease, diet and physical inactivity have been studied widely by researchers to understand if they induce lung cancer. Although scant statistics are available, researchers believe that diet and physical inactivity are linked with lung cancer. A study has shown that too much weight and low dietary fiber intake cause lung cancer. Moreover, a low fruit and non-starchy vegetable diet can induce genetic changes to cause lung cancer.
