What are the causes of lung cancer other than smoking?

Causes. Some of the non-tobacco related causes of lung cancer include: Radon – Exposure to radon gas in our homes is the leading cause of lung cancer in non-smokers. Asbestos exposure – Exposure to asbestos on the job is an important cause of mesothelioma, a cancer of the lung lining.

Also to know is, what percentage of people with lung cancer have never smoked?

Overall, 10 percent to 15 percent of lung cancers occur in non-smokers. (Another 50 percent occur in former smokers.) Two-thirds of the non-smokers who get lung cancer are women, and 20 percent of lung cancers in women occur in individuals who have never smoked. This percentage is significantly higher in Asian women.

What are the symptoms of lung cancer in a non smoker?

    Lung cancer starts when abnormal cells grow out of control in the lung. They can invade nearby tissues and form tumours. Lung cancer can start anywhere in the lungs and affect any part of the respiratory system. The cancer cells can spread, or metastasize, to the lymph nodes and other parts of the body.

    Who is most affected by lung cancer?

    Lung cancer can affect anyone. However, it occurs most commonly in people who smoke cigarettes. Others at risk include people who are exposed to secondhand smoke or those who have environmental risk factors, such as exposure to radon gas, asbestos, arsenic, silica, and chromium.

    What causes lung cancer in smokers?

    How does lung cancer spread through the body?

    Most lung cancers first spread to lymph nodes in the chest near the tumor. As cancer progresses, cancer cells can travel to areas in the chest further from the initial tumor, and then on to other regions of the body. Most of the time, the spread of lung cancer to the lymph nodes doesn’t cause any symptoms.

    What is the main cause of lung cancer?

    About 80% of lung cancer deaths are caused by smoking, and many others are caused by exposure to secondhand smoke.
