Causes Of Lung Cancer

Radon GasIn the entire world, lung cancer is mainly responsible for death tragedies that occur in both men and women. The main cause of lung cancer are carcinogens from tobacco products such as cigarette smoke, cigar smoke, pipe smoke and other harmful gas. Smoking is responsible for 80-90% of lung cancer disease, those who smoke cigarette are more likely to develop lung cancer quicker as compared to non-smokers, and it always occur at a high level. Inhaling the smoke from other people’s cigarette can also cause lung cancer.

However, cigarette smoking which is widely recognized as one of the main causes of lung cancer should be avoided if possible because it contains 7000 chemicals of which majority are poisonous. Smoking is addictive, it is the main reason smokers continue to smoke even at the risk of their health and they can’t help it but to continue smoking. The more someone smokes, the more is the risk of developing lung cancer. But, if a smoker tries every possible means to stop smoking, and eventually succeeds before cancer cells develops, the damaged lung tissues will begin to get repaired and the risk of developing lung cancer will reduce. The percentage risk will not be as low as that of those who doesn’t smoke.

Moreover, radon gas is another main cause of lung cancer, the presence of it in homes, and populated areas makes it one of the main causes of lung cancer in the world. Another cause of lung cancer is abnormal gene, the kind of gene one possesses can be responsible for lung cancer. Some inherited genes causes mutation which cause certain changes in the DNA of lung cells. It is actually these changes that lead to abnormal cell growth within the lungs. If the gene that is responsible for normal cell growth gets corrupted, it results to changes in the DNA which causes the cells to malfunction, these changes results to the development of lung cancer. Causes of lung cancer such as gene mutation cannot be avoided, it is mostly inherited, and little can be done to avert the imminent tragedy of lung cancer.
