Wildfire smoke exposure linked to higher head and neck cancer risk
A Harvard University study linked wildfire smoke exposure to higher head and neck cancer risk.
Researchers analysed 16 years of data on wildfires and cancer cases.
Exposure was linked to a 6 per cent higher risk, rising to 41 per cent among people exposed every year.
The concern comes as the UK and Europe experienced one of their most severe years for destructive wildfires on record.
Wildfire smoke contains PM2.5 particles, which the study says can raise cancer risk when inhaled and are more hazardous than particles from traffic fumes.
The findings add to evidence of health risks from wildfire air pollution, and researchers said stronger regulations are needed to reduce the impacts of climate change.
A Harvard University study found that exposure to wildfire smoke pollution was linked to a higher risk of head and neck cancer.
The reported risk was 6 per cent higher among people exposed to wildfire smoke, rising to 41 per cent for those exposed every year.
The article says wildfire smoke contains microscopic particles known as PM2.5 and describes its pollution as ten times more hazardous to health than traffic fumes.
The findings were published in The Laryngoscope.
- Who
- Researchers from Harvard University analyzed the data.
- What
- The study found an association between wildfire smoke exposure and higher head and neck cancer risk.
- When
- The analysis covered 16 years of data. The article was published on 25 October 2026.
- Where
- The researchers were from Harvard University in the US. The data concerned wildfires and head and neck cancer.
- Why
- The researchers linked the increased risk to air pollution from wildfires, including PM2.5 particles.
This story does not have two clearly opposing sides.

What people are saying
These results build on the growing body of evidence linking wildfire air pollution to adverse health and underscore the need for strengthened regulations to mitigate the impacts of climate change.
