Scientists have proven that smokers' lungs can fully recover, but under one condition

Your lungs have an almost magical ability to cure carcinogenic mutations caused by smoking, scientists said. But only if you quit smoking, writes Air force.

Mutations leading to lung cancer were considered permanent, forever remaining even among former smokers who no longer touch cigarettes.

However, the unexpected results of a study published in the journal Nature indicate that the few cells that have remained intact can repair the lungs.

This effect was observed even in patients who smoked a pack of cigarettes a day for 40 years before quitting.

The chemical elements contained in tobacco destroy the DNA of lung cells, which eventually mutates, slowly transforming them from healthy to carcinogenic.

Studies have shown that this occurs in the smoker's lungs even before the onset of cancer.

Most cells taken from smokers' airways mutated when exposed to tobacco. Such cells contain up to 10 thousand genetic changes.

“It's like time bombs waiting for the next blow to cause cancer,” says Dr Kate Gowers, a researcher at University College London (UCL).

But a small fraction of the cells remain intact.

It is not clear how these cells avoid genetic mutations caused by smoking. Researchers say it's like they "exist in a nuclear bunker."

But when a smoker quits smoking, it is these cells that begin to grow and replace damaged cells in the lungs.

In those who quit smoking, up to 40% of the cells in their lungs may look exactly the same as in people who have never smoked.

"We were completely unprepared for this discovery," Sanger Institute researcher Peter Campbell admitted to the BBC.

“There are a certain number of cells that somehow magically restore the airways,” he claims.

“Wonderful examples are patients who quit smoking after 40 years, and they began to regenerate cells that were not damaged in any way by tobacco,” the scientist notes.

Good reason to quit

Scientists have yet to understand the extent to which the lungs of former smokers are able to recover.

The study focused on the main airways and did not specifically examine the alveoli, microscopic lung structures involved in the body's use of oxygen.

In the UK, about 47 thousand diseases of lung cancer are diagnosed annually. Almost three quarters of them are related to smoking.

In Russia, according to the data of the National Medical Center for Radiology of the Ministry of Health, more than 62 thousand cases of such diseases are detected. About 50 thousand people a year die from lung cancer in Russia.

However, according to studies, people who quit smoking, already from the first day without tobacco, reduce the risk of lung cancer.

Previously, this was due to the fact that no further cell mutation occurs in quitters.

"This idea is really motivating: people who quit smoking get a double benefit - they prevent further damage to lung cells and give their lungs the chance to repair the damage already done with healthier cells," says Dr Rachel Orritt, an expert at Cancer Research UK. .
