The Top Causes Of Lung Cancer

Updated on March 22, 2011

There are a lot of lung cancer causes. This is the reason for the disease to be one of the top killers. The person who is suffering from lung cancer is at a very high risk of being affected with severe morbidity and even mortality. Every person will benefit from knowing the causes of cancer. This will help you to reduce the risks and may even help you to prevent suffering from lung cancer.

Smoking: This is the top cause of this disease. Lung cancer is almost synonymous with smoking. Any person who is a smoker is at a very high risk of being affected with lung cancer. There are very few smokers who do not suffer any damage to their lungs. Smoking cigarettes can lead to lung cancer more commonly than any other kind of smoking. Tobacco contains various substances like nicotine that can lead to cancer because it is a carcinogenic or cancer causing substance.

Passive smoking: Those who are not smokers, but live in the place where other people smoke are also at a high risk of lung cancer. This is because the person may inhale the smoke of other people. This can cause lung caner.

Asbestos exposure: Any person who is exposed to asbestos in the place of work or even in other places are at a very high risk of being affected with lung cancer. This is also one of the most common causes for industrial compensation.

Radon gas: Any person who is exposed to radon gas can also suffer from lung cancer. Radon gas is used in various industries. Wearing masks will help to prevent exposure even if there is a leak of the gas.

Hereditary causes: One of the other common causes of lung cancer is the hereditary cause. Any person who has had a parent suffering from cancer is at a very high risk of suffering from this disease.

Previous lung disease: Any person who has had a history of suffering from some kind of lung disease is at a very high risk of suffering from lung cancer. This is because of the injury and damage to the lungs that is pre-existing.

Metastases: Though a person may suffer from other kinds of cancer like breast cancer, the metastases of the tumor can lead to lung cancer in the person.

These are the common lung cancer causes. It is very important for every individual to make sure that if they are at high risk of being affected with lung cancer, they should reduce the risk and also undergo regular health checks. Cancer awareness is important in preventing and treating cancer early.

      Hello, Happy New Year to you. Important hub. My mother died of lung cancer seven years ago on Christmas morning. I'm fortunate that neither myself or my children smoke. Thanks.

      I had lung cancer about three years ago. It may have been from smoking although I haven't smoked for over 25 years.
