Cigarette Smoking - Principal Risk Factor for Lung Cancer

Cigarette smoking is the main risk factor for lung cancer. The cancer research demonstrates that the risk of getting cancer of the lung is higher amongst the cigarette smokers than the nonsmokers.

The risk of former smokers to grow cancer of lung will rise during the first 3-5 years after smoking cessation. However, why they end from smoking? Most of them is due to they are symptomatic and might already possess a number of critical diseases.



While active smoking has been exposed to be the major cause of lung cancer, second-hand smoke contains the same carcinogens even worse that are inhaled by smokers. Unluckily, the second-hand smoke has an effect on the nonsmokers as well. Reactive oxygen species is one of the environmental chemicals that toxic to our body. During passive smoking, the body is attacked by an excess of free radicals which inducing oxidative stress. Consequently, even a short period of passive smoking will break down serum antioxidant defense of the nonsmoker.

In addition, the elements of tobacco smoke stimulate oxidative DNA damage too. This oxidative DNA damage is connected to an increased risk of developing a number of degenerative chronic illnesses which comprises coronary heart disease and the dysfunctional cells (cancer).
