Wildfire Pollutants Increase Risk of Lung, Brain Tumors

Long-term exposure to wildfire smoke increases a person’s risk for developing lung and brain cancer by 5% and 10%, respectively, according to study findings published in Lancet Planetary Health.

Researchers analyzed data from the Canadian Census Health and Environment Cohort of more than 2 million people who had been followed for a median of 20 years for a total of 34 million person-years. They defined exposure to wildfires as living within a 20 km or 50 km radius of a burned area and estimated the correlation with specific cancers associated with wildfire carcinogenic compounds, including lung and brain cancer, non-Hodgkin lymphoma, multiple myeloma, and leukemia.

They found a 4.9% increased risk of lung cancer among those within either radius of a wildfire within the past 10 years and a 10% increased risk of brain tumors but no increased risk for hematologic cancers.

“Further work is needed to develop long-term estimates of wildfire exposures that capture the complex mixture of environmental pollutants released during these events,” the researchers concluded.
