Human genes can be mutated by smoking.
(Baonghean.vn) - In addition to causing mutations in 150 genes in lung cells, tobacco also causes 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 serious genetic damage in various organs of the body caused by smoking.cigaretteAnd it was found that in addition to causing mutations in 150 genes in lung cells, tobacco also causes 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 states: 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 research, scientists discovered that people who smoke one pack of cigarettes a day may cause an average of 150 gene mutations in their lungs each year, 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, approximately 6 million people worldwide die each year from 17 types of cancer believed to be linked to smoking. Cancer is caused by mutated cells that divide exponentially and uncontrollably.
In a comprehensive analysis of tobacco-related cancers, researchers found mutations in the DNA of smokers. These mutations represent a chain of genetic damage that can ultimately lead to cancer, although these mutations may vary between cells in different individuals.
This is the first time scientists have presented alarming figures about the harmful effects of cigarette smoke on the body's genetic data. Not only does it cause gene mutations in the lungs, but other parts of the body are also significantly affected by cigarettes, as the carcinogens in cigarettes are found in most organs that come into direct or indirect contact with smoke.
Cigarettes are a widely used stimulant in life. In particular, men and those with stressful, high-pressure jobs are often frequent smokers, using it as a habit, a way to express themselves, or to relieve stress.
