Called another harmful property of Smoking

Названо еще одно вредное свойство куренияSmoking causes gene mutations

The genes of smokers, a habit which often leads to a hospital bed, exposed to a huge number of mutations, said researchers.

A team of biotechnologists from the California compared the genetic changes in the lungs of a smoker, a cancer patient, with the genes of a healthy person and found about 50,000 changes. No one has previously reported the high number of mutations. Most likely, this is due to the Smoking patient, and this can not but cause concern, experts say. The study was published in the journal Nature.

Smoking is the main cause of lung cancer, and, according to recent reports, mutations in the genes come from each smoked cigarette. However, it is not so simple. The body tries to fight the harmful effects of Smoking and DNA processes by which the body “repairs” itself. Over time this protection wears out and becomes less effective, the expert explained.

The results of the study should alert all smokers and encourage those who are going to quit this harmful habit. Imagine what changes the genotype is exposed to during the years of Smoking, and think twice before you smoke, scientists warn.
