Smokers can turn back time in their lungs by kicking the habit, with healthy cells emerging to replace some of their tobacco-damaged and cancer-prone ones, a study shows.
Smokers have long been told their risk of developing diseases like lung cancer will fall if they can quit, and stopping smoking prevents new damage to the body.
A study published on Thursday in the journal Nature found that the benefits may go further, with the body appearing to draw on a reservoir of healthy cells to replace smoke-damaged ones in the lungs of smokers when they quit.
Sorta inherent in the very idea of cancer, isn’t it? New cells turning up, old ones dying off? Cancer being when this happens in an uncontrolled manner?
