Lung cancer occupies the second place in the list of most common kinds of cancer cases around the world. Most people believe that smoking causes lung cancer. However, you will be surprised to know that those people who have never touched cigarettes in their lives are also getting lung cancer. In non-smokers, cases of lung cancer are increasing rapidly and about 20 percent of cases of lung cancer are seen only among those who do not smoke.
Vince Cancer Lam, a lung cancer specialist at the University of Texas Cancer Center in Houston in US, says cancer that occurs in smokers and cancer in non-smokers is completely different. Non-smokers who suffer from lung cancer are much younger than smokers and most non-smokers who suffer from lung cancer are women.
According to the doctors, there are some common reasons why even those who do not smoke cigarettes are getting lame cancer.
Even if you have never smoked cigarettes yourself, but if you live with smokers, then tobacco smoke will also enter your body and the risk of lung cancer will increase. 25 percent of non-smokers living with smokers are at risk of lung cancer. Every year in the US, 3 thousand people die of lung cancer due to passive smoking.
We all know that about 90 percent of the world’s population is breathing in polluted air. Given the rapid increase in the rate of air pollution, it is not difficult to guess how much damage would be caused when this polluted air enters the lungs. Due to prolonged breathing in polluted air, a large number of people are getting lung cancer.
When uranium decays, a gas is released from it called Radon and exposure to this gas for a long time increases the risk of lung cancer. Radon gas is under the ground but many times if there is some kind of gap in the house, then it can also reach inside the house through pipeline or drainage. Since this gas has no color or smell, it is difficult to identify.
