Reasons Why Smoking Tobacco Cigarettes Creates Cancer of the Lung

Is there anyone that doesn't know that smoking cigarettes is an unhealthy activity? Too many people have suffered prolonged and debilitating diseases and many have died as a result of tobacco smoke. If you do not die of a tobacco related disease your lifestyle may be severely curtailed as a result of lung function impairment.

We in all probability all understand that people continue to smoke cigarettes because they are hooked on nicotine. After a period of prolonged smoking, the body requires nicotine so as to feel good. The dependency occurs when you grow to be irritable without a supply of nicotine. The extremely fast return to a normal feeling when smoking a cigarette makes smoking among the strongest addictions know to man.

Cigarette smoke is primarily composed of gases like nitrogen, oxygen and carbon dioxide. But, it's the 3500 to 4000 other chemical compounds within the smoke that cause the damage. Approximately 55 of these compounds are carcinogens that can cause a variety of cancerous tumors in laboratory animals or humans. At least 20 of these compounds are know to promote lung tumors in no less than one animal species.

Here's how this works. Compounds like 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) or polycyclic aromatic hydrocarbons produce cancerous tumors. These compounds attach or bind to DNA and damage the DNA structure. When the DNA cells attempt to replicate, a mutation can result and begin a cancerous tumor.

Growth of mutated cells can usually be controlled. Some cells can be repaired, others programmed for early death, and some prevented from additional multiplication. But, if these mechanisms of abnormal cell management themselves turn out to be damaged, normal growth management fails and the cells reproduce in an uncontrolled fashion. Uncontrolled multiplication of cells represents a cancer and can proliferate past the lungs to adjacent organs.

Other compounds in tobacco smoke must transition through chemical changes before they can bind to DNA and begin their destruction. Whether it is a direct attack on the DNA or an indirect chemical transformation, its these DNA adducts that cause the uncontrolled replication we describe as a cancer.

You'll be happy to discover that over 80% of people who smoke never get lung cancer. But, no smoker is totally immune from the harm from the tars and other compounds found in tobacco smoke that restrict the complete function of the lungs. Many individuals without lung cancer require oxygen and have drastically reduced lifestyles as a result of cigarette smoking.

The most important advice is to quit smoking. Risks of lung cancer diminish significantly after 5 years of non-smoking.

If you've tried to give up smoking but have found the dependency on nicotine too strong, you can nonetheless get the nicotine your body needs without the tars and other compounds found in tobacco smoke. The new smokeless cigarettes vaporize a small amount of nicotine with each puff and some optional flavoring, but provide no tars or other dangerous compounds. You in all probability have seen commercials for these products. Reduce your chances for lung cancer, give up smoking, and take a look at the smokeless cigarettes for your own health.
