Smoking and lung cancer are terms that are commonly used in various situations. There are many people who have been suffering from diseases of the lungs and some of them suffer very severe problems and a very few of them may even suffer from lung cancer. The truth is that the relation between smoking and lung cancer is very high.
There are various reasons for this. The first important factor is that the smoke from the cigarettes contains nicotine that is released from the tobacco. The nicotine is a very addictive substance and at the same time, it is also a carcinogen. A carcinogen is a substance that can cause cancer in a person. Since the nicotine is a carcinogen, it can cause cancer in the person.
The nicotine enters the lungs of the person with each breath when the person draws in the smoke. Once this occurs on a regular basis, the person will start having changes in the tissues of the lungs. The lungs start collecting fluids and there is also infection. The air that enters into the lungs is also not to the full amount. This decreased air entry into the lungs will cause the person to suffer from breathlessness.
Other than the person who smokes, the people who live around the smoker can also be affected by smoking and this is called as the passive smoking. Since the affected individual is not an active smoker, the inhalation of the smoke that is exhaled by a smoker is called as passive smoking. The passive smoking also has the same kind of effect as active smoking. The family members or people living with a smoker are prone to this condition and may also suffer from lung cancer. Cessation of smoking decreases the chances of a person suffering from lung cancer very drastically.
