Causes of Lung Cancer
It is a known fact that smoking causes lung cancer as tobacco contains substances that are known carcinogens. The risk of developing lung cancer is also high in passive-smokers. The other known causes of lung cancer which is not related in any way to smoking is as follows:
• Over exposure to radiation on account of one’s profession or having had medical treatments in the past.
• Working in an environment that is exposed to asbestos, and products involving coal, arsenic, vinyl chloride, nickel chromate etc which are extremely harmful to the body. Working in the construction industry or in mines can also cause lung cancer.
• In certain areas the poisonous gas, Radon, occurs naturally in the rocks and soil. Radon is known to be a cause of lung cancer.
• After serious research it has been deduced that certain sections of people whose body is unable to deal with certain chemicals that cause cancer are more at a risk of developing it. The immune system of such people instead of neutralizing some particular cancer-causing agents within the body, make them more aggressive.
