What types of cancer can be caused by smoking? How are cancer of lungs and smoking connected? Read the information below to learn more facts about it.
What cancer does smoking cause?
Nowadays almost everyone knows an answer to the question: what cancer do cigarettes cause? Every year the number of people who faced oncologic diseases grows. Statistically, the most widespread of them is lung cancer. It is known that men suffer from this lethal disease 7-10 times more often than the women do. Besides, with age, the risk of developing lung cancer is considerably enlarged, and at 60-69-year-old men, the case rate is 60 times higher in comparison with 30-year-old men.
The factors promoting development of lung cancer
Scientists from around the world conduct numerous researchers for the purpose of research of the causes of cancer tumors. At the moment, it is possible to tell with absolute confidence that constant smoking causes cancer. Cigarettes contain a huge number of harmful carcinogenic substances, of which contains at least third of the smoked cigarette. At constant smoking, these substances are collected in an organism and lead to deformation of structure and disturbance of normal work of internal bodies. These changes, eventually, lead to developing of malignant tumors. Researchers showed that in 90% of cases smoking is the reason for lung cancer. Dependence between the quantity of the smoked cigarettes and risk of emergence of cancer is obvious. Moreover, at smokers, the probability of death is much higher. An important factor also is the quality of cigarettes. Choosing cheap cigarettes without the filter, the smoker receives low-grade tobacco, which represents the special danger to his or her health.
Smokers should remember that they endanger not only their own life but also the life of the relatives & people around. The matter is that even passive smoking causes lung cancer. Statistically, members of the family of the smoker have cancer tumors1.5-2 times more often than in non-smoking families.

Cancer and smoking
Everybody knows that lung cancer and smoking are two close companions. However, other factors, for example, the strong smoke of city air, exert an impact on the development of malignant tumors too. Work with toxic and harmful substances, such as nickel, chrome, asbestos dust, and others can also become the cause of oncologic diseases. The congenital and acquired illnesses of lungs and inflammatory processes increase the risk of emergence of cancer tumors. For the last several decades, the quantity of people with lung cancer increases. If 20 years ago men faced this horrible disease generally, then now at women malignant tumors are even more often formed. It is connected with the fact that smoking becomes a very widespread addiction among the female population either. Origin of cancer depends on duration and the frequency of smoking. Constant smokers become victims of cancer diseases 20 times more often than not permanent smokers. The known fact is that lungs, breast cancer and smoking are connected. However, the interesting tendency is watched recently: the number of the smoking men is reduced, and the quantity of people with cancer increases. There is a question: what can explain such strange circumstance? A lot of scientific researchers, directed to study between smoking and cancer were made. As a result, scientists concluded that the problem consists of the quality of cigarettes. Tobacco smoke contains a huge amount of carcinogens, which are the reasons of cancer diseases. Researchers made the list of the most dangerous of them.
Dangerous components of cigarettes
The nicotine in cigarettes can become the reason for cancer. In the case of combustion, the filling develops the substances belonging to the category of carcinogens. Besides, tobacco smoke contains other particles potentially dangerous to health: arsenic, nickel, and cadmium. Many smokers consider that the filter saves from the pitches and other problems in an organism. However, scientists deny safety of filters. Accidental inhalation of thin threads, of which filters are made, can become the reasons of cancer. For the purpose of an attraction of the bigger number of consumers, producers add various fragrances and dyes to tobacco. New tastes and aromas really attract smokers, especially young girls who forget that smoking leads to cancer. Of course, they don't even guess that in the case of combustion all these substances produce very unhealthy chemical substances. In addition to above-mentioned substances, cigarettes contain also other potentially dangerous components. Menthol, sugar, and different fragrances in most cases are a part of some kinds of tobacco. Scientists can't precisely determine yet what impact is exerted with all these substances on the smoker's organism.
Smoking and cancer of an oral cavity
Most often smokers connect smoking and lung cancer. However, recently oral cavity cancer became a very widespread phenomenon. According to the American scientists, one person dies of this type of cancer in one hour. The most terrible are that this dangerous disease even more often occurs among the people who didn't reach 40-year age. It means that cancer becomes younger with a wild speed.
The first sign of cancer of oral cavity are pains when chewing, the emergence of spots and erosion, a sleep of some parts in a mouth can be observed. According to the statistics, in 75% of cases patients are active smokers.
Smoking and other types of cancer
It is necessary to remember that smoking is the reason for cancer not only of lungs but of an oral cavity and other parts of an organism. Oncological diseases of skin, kidneys, and throat are also often provoked by this life-threatening habit.
