The share of non-smokers among diagnosed people also climbs. This proportion now represents around 1 in 4 cases in the world. In France, it is rather 2 in 10 people, or around 10,000 new cases per year.
Pollution causes genetic mutations
Several dozen researchers from around the world have joined forces to carry out a new study published on July 2, 2025 in the prestigious review Nature. Their results confirm the links between pollution and lung cancers. The more polluted a region, the more genetic mutations related to cancer in tumors taken. This is the first study that explains how pollution promotes disease. The researchers based on data from the Sherlock-Lung study. They analyzed the genome of 871 people who had never smoked, but still developed lung cancer. These patients were from 28 different world regions. “” Our research shows that air pollution is strongly associated with the same types of DNA changes as those that are generally associated with smoking “, Explains the Guardian Ludmil Alexandrov, doctor at the University of San Diego in California.
