The number of smokers in the world is going down, but lung cancer still causes almost 2 million deaths yearly. New research shows a rise in lung cancer cases among people who never smoked. Pollution, mainly in east Asia, is believed to be a significant factor.
A type of lung cancer called adenocarcinoma is becoming more common worldwide, especially in non-smokers. This cancer type mostly affects glands and is linked to air pollution.
The research team suggests that efforts to reduce smoking should continue, and measures should be taken to address the impact of air pollution on lung cancer cases. The study highlights the need to gather more data to understand and combat lung cancer better.
The findings provide valuable information for developing strategies to control tobacco use and air pollution, especially in areas with high rates of lung cancer. The research was published in The Lancet Respiratory Medicine.
