Firefighting Chemicals Linked to Increased Brain Cancer Risk

A study finds a potential connection between long-term exposure to haloalkanes and glioma development in firefighters.

Researchers identified a mutational signature in gliomas associated with exposure to haloalkanes, chemicals found in fire extinguishers and flame retardants.
The study analyzed tumor samples from 17 firefighters and 18 non-firefighters, revealing higher mutation rates in firefighters' tumors.
Non-firefighters with occupational exposure to haloalkanes, such as painters and mechanics, also showed similar mutational patterns.
The findings suggest a possible environmental risk factor for gliomas, though the study's small sample size calls for further research.
Experts emphasize the importance of identifying occupational hazards to inform public health strategies and preventive measures.
