Smoking and lung cancer are linked. The facts about what causes cancer of the lungs are more mysterious they are well established in the scientific literature. We now know smoking is what causes lung cancer in 85-90% of cases.
The carcinogenic effects of smoking cigarettes affect the tissue of the lungs over time and malignant tumours develop first in the bronchi and then in the rest of the lungs. Broncho-pulmonary means simply the fact that the cancer originates in the bronchial tissue.
History of lung cancer
The historical facts are clear enough. The use of tobacco had become common in cancer society in the lungs that was a very rare disease. The alarming outbreak of broncho-pulmonary followed in the wake of the tobacco industry, manufacturing, sale and distribution of their products of cigarettes in the first half of the 20th century.
Until that time, some clinicians noticed an increase in the number of cases, but mostly they were likely to be attributed to air pollution or industrial exposures to chemicals.
It was actually a German doctor who had the original link between smoking and lung cancer. He has published a paper in 1929 showed the connection and the hypothesis that lung cancer is caused by the smoke because almost all patients who have had the disease he studied were smokers.
Of course in the first half of the 1900s person did believe that the epidemic in the lung cancer had nothing to do with the harmful effects of tobacco. In fact, they do not even wanted to believe that smoking was harmful and that he wanted to continue to believe everything that tobacco said of them and that is that the effects of tobacco were relaxing and beneficial for the mind. People believed this because there is no facts to prove the contrary.
The actual facts on smoking and lung cancer had not yet established, although many clinicians have started to become very suspect. In the century, there was an alarming outbreak of broncho-pulmonary. The social acceptance of tobacco use among men, women and the increase in the number of smokers, the company could not be a coincidence.
The real facts on smoking and lung cancer are established.
Thus, the scientific study to find the actual facts on smoking and lung cancer and see if this German doctor was on something started seriously.
Perhaps it was the improvements in the rigors of scientific study, or perhaps even improvements in technology but nonetheless there are a lot of energy being conducted to discover whether broncho-pulmonary have been caused by smoking and over time, results have become so consistent that scientists began to reach the same conclusion again and again, is that lung cancer is caused by smoking.
Nobody wanted of course this is true, especially tobacco companies that were of billions of dollars from selling their products in the world. Apparently, they thought that it would be bad for the business if their product was associated with a disease as broncho-pulmonary that has always been a prognosis very dark.
Studies have continued over the years and findings of these studies are the basis for the first general report us surgeon on smoking and health in 1964. The known facts about smoking and lung cancer, at the time led to the conclusion that smoking was an important factor in the cause of lung cancer.
Other studies have now shown that fact over and over again, and forty years after the first report, the 2004 US Surgeon General report states: “the evidence is sufficient to infer a causal relationship between smoking and lung cancer.”
Those who are thus some historical lung cancer facts and smoking cigarettes. But all the facts on lung cancer the most important to pay attention to the is:
There is no other type of cancer is easily preventable.
