Human genes can be mutated by smoking.
(Baonghean.vn) - In addition to causing mutations in 150 genes in lung cells, cigarettes also cause mutations in 97 genes in the larynx, 39 genes in the palate, 23 genes in the oral cavity, 18 genes in the bladder, and 6 genes in the liver.
According to a recently published study, scientists have measured severe genetic damage in various organs in the body due to smoking.cigaretteand found that in addition to causing mutations in 150 genes in lung cells, cigarettes also cause mutations in 97 genes in the larynx, 39 genes in the palate, 23 genes in the oral cavity, 18 genes in the bladder and 6 genes in the liver.

The study said: Previously, we only found epidemiological evidence linking smoking to cancer, but now we are studying this issue at the genetic and DNA level. With this study, scientists discovered that people who smoke a pack of cigarettes a day on average each year can cause 150 gene mutations in the lungs, and this explains why smokers have a higher risk of developing lung cancer than non-smokers.
Scientists say that cigarette smoke contains 7,000 chemicals, including at least 70 carcinogens. Meanwhile, according to the World Health Organization, each year around 6 million people die from 17 types of cancer believed to be related to cigarette smoke. Cancer is a type of mutated cell that divides exponentially and uncontrollably.
In a comprehensive analysis of smoking-related cancers, researchers found mutations in the DNA of smokers. These mutations represent a cascade of genetic damage that can eventually lead to cancer, although the mutations may differ between cells in different individuals.
This is the first time scientists have presented startling figures about the harmful effects of cigarette smoke on the body's genetic data. Not only does it cause genetic mutations in the lungs, other parts of the body are also significantly affected by cigarettes, because carcinogens in cigarettes are seen in most organs that are directly or indirectly exposed to cigarette smoke.
Cigarettes are a stimulant that is used quite commonly in life. In particular, men and people with stressful jobs, a lot of pressure... are the subjects who often smoke cigarettes as a habit, a way to express themselves or release emotions.
