A research study led by Imperial College London and the University of Cambridge, and commissioned by the London Fire Brigade, has examined the long-term health of London firefighters, including those who responded to the Grenfell Tower fire.
The study explored whether there are early signs of potential health risks, such as cancer, by analysing blood samples for very small DNA changes that may be linked to illness.
A question-and-answer information sheet has been produced to help explain the findings in more detail.
What did the study find?
- 685 firefighters took part in the study
- 261 firefighters had detailed genetic testing, most of whom attended the Grenfell fire
- 11 firefighters showed a genetic change in their blood
- All 11 had attended Grenfell, but the number is too small to draw firm conclusions
- These DNA changes do not mean someone has cancer or will definitely develop it
- Similar changes can be found in people who have never been exposed to fires, and most people with these changes remain healthy
- There is currently no reliable blood test for early cancer detection available as a result of this study, for firefighters or the wider community
The findings will continue to inform ongoing research and monitoring.
