Scientists say that your lungs have an almost ‘magical’ ability, which can self-heal some damage caused by smoking.
Mutations that give rise to lung cancer are considered permanent and even after quitting smoking it is believed that it stays there.
But according to research published in Nature, some cells correct lung damage.
These effects have also been seen in patients who smoked a pack of cigarettes daily for 40 years before quitting smoking.
While smoking, tobacco contains thousands of chemicals that translocate lung cell DNA and gradually make it healthy to cancer.
In this research, it has also been found that even if there is cancer, it occurs on a large scale in the lungs of the smoker.
Such cells were taken from the lungs of smokers from airways which were converted from tobacco, there were 10,000 genetic changes.
“They can be considered a small bomb waiting for the next step that can turn into cancer,” says UCL researcher Doctor Kate Govers.
But a small part of the sales does not translate.
Why genetic changes occur due to smoking is not clear yet, but researchers say that they look like ‘nuclear bunkers’
However, when someone quits smoking, then these cells increase and the cells that have damaged the lungs are removed.
40% of the sales of people who have quit smoking are like those who have not smoked till date.
“We were not fully prepared for this research,” says Peter Campbell of the Sanger Institute.
He says, “There are a number of cells that magically replenish the lining of the airway.”
“The patient who quit after smoking for 40 years saw major changes. His sales were revived for those who were not exposed to tobacco.”
Motivation to quit smoking
Researchers still have to check how well the lungs heal. This research focuses on large airways of lungs while airways such as alveoli are not included.
Every year there are 47 thousand cases of lung cancer in the UK. Out of this, about three quarters of cases are caused by smoking.
Research shows that the risk of lung cancer starts to decrease from the day you quit smoking.
Doctor Rachel Oritt of Cancer Research UK says, “It’s really an inspirational idea that people can give two types of benefits by quitting smoking. They can save tobacco-causing lung cells and reduce their lung damage by reducing Can give healthy sales. “
