A reminder of the benefits of quitting smoking, particularly in younger people, to reduce the risk of lung cancer and ‘curability’. Of course, never smokers do best.
“In general, never smokers are healthier individuals, so they tend to, in a lot of trials, have better outcomes with disease than people who continue to smoke,” she [Amy Ferketich] said. “Just the continued exposure to tobacco might make the disease progress more quickly in smokers compared to never-smokers who don’t have that exposure.”
Ferketich said it’s also possible that smoking could influence the biology of the cancer, and perhaps smokers get tumors that never-smokers are less likely to develop. She added that it’s never too late to quit.
