Study Links Firefighting to Increased Risk of Brain Cancer from Chemical Exposure

Researchers identify genetic mutations in firefighters' brain tumors tied to haloalkane exposure, though findings remain preliminary.

A new study suggests firefighters may face a heightened risk of gliomas, a type of brain cancer, due to exposure to haloalkanes found in flame retardants and fire extinguishers.
Researchers identified mutational signatures linked to haloalkane exposure in tumors from 17 firefighters and 18 non-firefighters, with higher prevalence in firefighters.
The study, published in the journal *Cancer*, highlights the need for further research with larger sample sizes to confirm these preliminary findings.
Non-firefighters with similar mutations were often exposed to haloalkanes through occupations such as painting or auto mechanics.
Experts stress that understanding exposure-related genetic mutations could inform public health strategies to mitigate risks for firefighters and other affected groups.
