Air Pollution: The Hidden Killer Behind Lung Cancer

A groundbreaking study has revealed that air pollution is a significant contributor to lung cancer, particularly among those who have never touched a cigarette. This alarming research sheds light on the mysterious rise of lung cancer cases in non-smokers, labeling it as an "urgent and growing global problem."

Genetic Evidence Links Pollution to Cancer

Led by Professor Ludmil Alexandrov from the University of California, San Diego, researchers analyzed the complete genetic makeup of lung tumors from 871 non-smokers across various continents, including Europe, North America, Africa, and Asia. Their findings are startling: as air pollution levels increase, so do the number of cancer-promoting DNA mutations in tumors.
