Confirmed by researchers from the United Kingdom and Italy in the study they gave during Bliverbwol conference (England) this week, that smoking leaves chemical fingerprint of the history of nicotine addiction on the surface of the DNA to the smoker, which can be used to measure the risk of cancer in these persons.Although the genetic code of the DNA remains subject to change, the smoking history leaves its impact on the surface of the DNA, which is referred to as "the evolution Alladeneioa amendment" or epigenetic modification. This amendment does not modify genetic code in DNA, but it affects on how to interpret them.The researchers work two Musatin studies the emergence of DNA Alladeneioa blood to search for chemical growths at 374 healthy people, injured half later breast or colon cancer. The researchers examined the relationship between the presence of chemical growths in the DNA of the person and the position of smoking as well as the risk of cancer.Researchers have discovered the existence of many chemical appendages when current smokers and to a lesser extent when ex-smokers, while not detected only six of these polyps in people who have never smoked.The researchers found that these chemical appendages gradually fade as soon as the person that takes off from smoking, but the DNA of the former smoker is not due to DNA similar to the person who has never smoked.He said one of the researchers: "This may help search in the test mode can measure in great detail the risk of cancer in smokers," adding that "previous research in the effect of smoking was often rely on lists questionnaire filled person for his habit and that may not be sufficiently precise to reap accurate results, but the new research this method will enable us to read fingerprints smoking on the DNA of a person and how it caused the habit to change the course of his life.
