It is neither a myth nor belief that smoking causes lung cancer. This is a fact since it has been examined by clinical officer and the underlying truth revealed. Smoking is the major cause of lung cancer according to recent clinical studies. The tobacco smoke leads to chronic disease and also contributes to the cancer of kidney, bladder and pancreas. In simple terms, we can say that smoking causes lung cancer plus other complications that can result to death in not realised early in advance.
How does smoking cause lung cancer? It is true that smoking causes lung cancer and this is how it happens: it is true that the lung is lined with very many tiny hairs known as cilia. Cilia play a great role in protecting the lungs from unwanted materials. They act like small brooms which sweep away the dust or tar that gets attached to the air tubes inside the lungs. Cilia try to push these unwanted materials upward until they are spit out of the lungs. Once an individual takes a puff of cigarette, the smoke slows down the functioning of the cilia.
This process continues for quite a long time until all the cilia get damaged and thus they cannot perform their function any more. As a result, the dust or tar particles that had been trapped by the cilia become absorbed into the nearby cells which form the lining of the air tubes. This is because the cilia are dead now and cannot function anymore. The result will be accumulation of these harmful substances into the lungs and bring about lung infections. This constant irritation continues for quite a long time without the knowledge of the victim. Eventually, it turns to cancerous cells which lead to lung cancer. The transformation actually takes several years but once it starts, it cannot stop its progress. These cancerous cells continue to eat the walls and cells inside the lungs deeper and deeper. By the time some signs get noticed, the whole thing will actually be out of control and the person has no other option other than to wait for the fate. This is how smoking causes lung cancer.
It is worth to note that lung cancer takes between 55-65 years to fully develop in the lungs of a smoker. Once a person starts smoking, changes in his or her lungs start immediately. The problem is that he or she cannot realise the changes simply because they take place inside the lungs. The best thing to do is learn about the dangers of smoking and decide to quit completely. Awareness on how smoking causes lung cancer would be the best lesson for him or her and can make him or her change the attitude. Once the person is exposed to carcinogenic chemicals, funny complications starts to develop and the person can feel the changes although he or she ignores.
Once the person is exposed to these carcinogenic chemicals from tobacco, a number of abnormal cells start to develop in the bronchi lining which are the main breathing tubes. The number of abnormal cells continues to develop as long as you expose yourself to these harmful substances. These abnormal cells are actually cancerous and are the major cause of lung cancer. The situation is actually worse for those who have been addicted by nicotine. This is because addiction is very bad since the person does not feel like to stop smoking. If he or she continues with the habit of smoking, these abnormal cells continues to develop and eventually land him or her in trouble. Therefore, it is good to realise that smoking causes lung cancer and quit smoking if possible.
Once an individual stops smoking, the risk of getting lung cancer decreases. Stopping smoking will make the abnormal cells to get replaced by normal cells over time. After around 10 years of quitting smoking, the risk of getting lung cancer slows down and the person can now be proud since he or she is just like a non-smoker. For those who happen to resume smoking again, the risk of getting lung cancer continues to increase and eventually, the situation will be beyond control since he or she will be diagnosed with lung cancer. Since we are aware that smoking causes lung cancer, there are also other related complications that smoking can lead to. These include; heart diseases, stroke, emphysema and chronic bronchitis. There are various facts about lung cancer. One of them is that lung cancer accounts for approximately 32 percent of cancer deaths in men, and 25 percent in women.
It is good to be aware of how smoking causes lung cancer. This will help you make up your mind fully and decide whether you can leave smoking or not. If you read well about lung cancer, it is true that you cannot stand your habit anymore. You will throw away the cigarette in your pocket and quit smoking for good.
