Know the abilities of the lungs to correct the damage caused by tobacco

This happens only in cases where people leave this bad habit

The lungs are the organs that suffer most from smoking. In fact, smokers are more likely to have lung cancer than other people. But you should know that these have splendid abilities to recover in case you decide to leave the vice. Know, below, what are the abilities of the lungs to correct the damage caused by tobacco.

What are the abilities of the lungs to correct the damage caused by tobacco

It may seem incredible, but it is. There are some abilities of the lungs to correct the damage caused by tobacco, as long as you stop smoking. In this case, the organs can restore the cancerous genetic transformations caused by the cigar, according to new scientific research.

What was believed until before was that the mutations that cause lung cancer were continuous and were maintained even if the person quit tobacco? However, according to the BBC, referring to the study published in the journal Nature, the cells that manage to escape the deterioration caused by cigarettes could repair the lungs.

It should be noted that the result was even seen in people who had been smokers of a pack of cigarettes a day for 40 years before deciding to quit smoking.

How was the study

It should be taken into account that the chemicals present in cigarette smoke cause the DNA of healthy lung cells to suffer mutations. The consequence is that they become cancerous.

The lung biopsy of 16 smokers and ex-smokers was evaluated in the investigation. Also of adults who had never smoked and children. What they say is that the mutations take place on a large scale in the lungs of people who smoke even before they develop cancer.

Both the airway cells of ex-smokers and smokers had suffered alterations or mutations due to cigarettes. Moreover, there were cases of up to 10,000 genetic changes.

Dr. Kate Gowers, one of the authors of the finding, said that "these mutations can be considered as mini bombs of time waiting for the next blow that makes them become cancer."

The conclusion was that 9 out of 10 cells in the lungs of people who continue to smoke had mutations. However, the rest were unharmed. This causes that, at the moment they leave the vice there are abilities of the lungs to correct the damage caused by tobacco.

This is because the unharmed cells grow and replace those that were damaged. In the study, they showed that in the ex-smokers, 40% of their cells were similar to those individuals who had never smoked.

Since the sample size was small, research should continue as there are many questions that remain to be resolved.
