Scientists from the University of Minnesota conducted an experience that proved the relationship of smoking with cancer. Professor Stephen Hecht had a profound study of the mechanisms of metabolic activation and DNA modification carcinogens from cigarettes. For volunteers, scientists tracked the traumatic impact of tobacco on the DNA, which can make a smoker with cancer.
The American scientists from Minnesota proved devastating impact of tobacco products on the collapse of the DNA of the smoker. Transformed into a variety of substances, components of tobacco smoke is inevitably contacted with human DNA, causing irreversible reaction. One of them may be a cancer. Check a scientific hypothesis about how long it takes a smoker on to become cancer patients, Professor Hecht suggested volunteers. The experiment confirmed the association between smoking and cancer.
Scientific experiment with volunteers-smokers showed a detrimental effect of smoking on the internal organs. Moreover, the effect of tobacco smoke starts with the first puff. The decomposition products of tobacco smoke will inevitably cause damage to the cell and into contact with the DNA – so become a smoker with cancer is not difficult. “Cigarette smoke contains more than 70 carcinogens,” says Professor Hecht. Regular poisoning of cell membranes and DNA weakens the defense cells and can give impetus to the growth of “sleeping” cancer cells anywhere in the body of man
Tobacco smoke causes cancer mutations in human cells, and, smokers experience a completely unimportant:. Ravages of products decay tobacco smoke can not neutralize DNA. The most toxic compounds in tobacco smoke, according to scientists, is phenanthrene. Peak concentrations in the body occurs in 15-30 minutes after the smoked cigarette. A smoker can become cancer patients in a very short period of time.
This experiment once again shows that smoking not only causes lung cancer. This habit is a common cause of heart disease, stroke and others. Passive smoking leads to the same diseases. It is reported that tobacco smoke has another pernicious effect. He quickly, within a few seconds, destroy any cells in the body, even these hardy as liver cells. At the same time destroyed the DNA helix. This can lead to dangerous genetic diseases of the fetus in pregnant women.
Recall that the incidence of malignant tumors, is continuously growing. Annually in the world registered about 6 million new cases of malignant tumors of the disease. The highest incidence among men is marked in France (361 per 100 000 population), among women in Brazil (283.4 per 100 000). This is partly explained by the aging of the population. It should be noted that most tumors developing in individuals older than 50 years, and every second cancer patient older than 60 years. The most commonly affected prostate and lung in men and breast cancer in women. The death rate from cancer is ranked third in the world, followed by diseases of the cardiovascular system and respiratory system diseases (including COPD)
