The Claim

In 2021, the incidence of lung cancer among women under 65 years of age exceeded that among men under 65 years of age for the first time, with rates of 15.7 per 100,000 women and 15.4 per 100,000 men, which is attributed to women adopting smoking later and quitting more slowly than men.

For the first time in 2021, more women under 65 got lung cancer than men under 65, likely because women started smoking later and had a harder time quitting compared to men.

Lung cancer incidence in women under 65 years surpassed that in men for the first time in 2021 (15.7 vs. 15.4 per 100,000), reflecting later adoption and slower cessation of smoking among women compared to men.
