A new study revealed that people who smoke "heavily" throughout their lives, can still significantly reduce the risk of developing lung cancer by quitting smoking.
The study gave hope to heavy smokers who quit smoking, stressing that it is not too late to stop or quit this bad habit, even after 30 or 40 years of intensive practice.
Scientists have claimed that the latest discovery, made in a study by the Wellcome Sanger Institute and University College London, provides smokers with long-term hope.
The study found that compared to current smokers, people who quit smoking have more genetically healthy lung cells, with the growth of new healthy and healthy cells, so that the lining of the airways is regenerated. And the cells, in turn, become less likely to develop cancer in the future, according to the British newspaper, The Independent.
"People who have smoked heavily and intensely for 30 or 40 years or more tell me that it is too late to quit smoking, and that the damage has already occurred," the British newspaper quoted the study’s chief researcher and researcher at the Wellcome Sanger Institute, Peter Campbell.
He added: “The exciting thing in our study is that it is not too late to quit smoking. Some people in the study smoked more than 15 thousand packs of cigarettes throughout their lives, but after a few years of quitting smoking, many bronchial cells recovered in The lungs are their lining, and no evidence of tobacco harm has emerged. ”
It is worth noting that out of the 47,000 lung cancer cases reported in Britain every year, about 72% of them are believed to be due to smoking, which is 21% of all cancer deaths, according to the Cancer Research UK.
According to the study, the results of which were published in the journal "Nature," researchers analyzed lung biopsies of 16 people, a group that included smokers, former smokers, people who had never smoked, and children.
