Smoking’s negative health consequences are well known, but smokers can reduce―or even erase―their risk of dying from lung cancer by quitting at a young age, and the younger the better.
“Smoking definitely has a cumulative effect,” said Dr. Patrick Ma, an oncologist at Penn State Cancer Institute. “Of course, the best advice is never start smoking, but this study shows it’s never too late to quit and see some benefit.”
On the flip side, the sooner one starts smoking, the higher their chances of dying from cancer. People who started smoking before age 10 are four times more likely to die from cancer than lifelong nonsmokers, and people who started before age 18 are three times more likely.
The good news overall is that lung cancer-related deaths are on a downward trend, Ma said. Lung cancer mortality among men has decreased by 51 percent since 1990 and by 26 percent among women since 2002.
Annual scans for lung cancer are recommended for adults ages 50 to 80 who have smoked at least one pack of cigarettes for 20 years and currently smoke or have quit within 15 years.
