More evidence it’s never too late to stop smoking | Instant News


It’s never too late to stop smoking in terms of survival from lung cancer.
Researchers in Canada studied more than 35 thousand patients with lung cancer.
They found that ex-smokers who quit more than five years before being diagnosed were 20% less likely to die than current smokers.
But even those who stopped the habit only two years earlier had a 12% lower risk of death.
Long-term heavy smokers are also more likely to survive if they stop before developing lung cancer.
The study was led by researchers in Canada and presented at a meeting of the American Society of Clinical Oncology.
