The researchers compared new cancer cases among 10,786 New York City firefighters who worked in these facilities after the attack, with 8,813 firefighters who did not do so and participated in health research.
Madrid. (EUROPA Press)-Firefighters who worked in the World Trade Center following the September 11th 2001 attacks are 13% more likely than their colleagues to develop cancer, particularly thyroid cancer and prostate cancer. Journal of Occupational and Environmental Medicine. The results also showed that the average age of the patients was 4 years older at diagnosis.
Researchers believe firefighters are frequently exposed to carcinogens in their work but it isn’t clear if their risk of developing the disease has increased.
Complicating matters is the toxic environment at the World Trade Center, which exposes firefighters and their families to harmful substances such a polychlorinated Biphenyls (PCB), benzene, arsenic and polycyclic aromatic Hydrocarbons (PAH), as well as asbestos, sulfuric acid (Sulfuric Acid, Benzene, and benzene.
The researchers compared the new cancer cases in firefighters with those of 10,786 firefighters in New York City to that of 8,813 firefighters at the World Trade Center after the attacks. Those who didn’t participate in this study were included in the Occupational Firefighter’s Health Study (CFHS).
The World Trade Center firefighters were ranked based on their level of exposure to harmful chemicals. 911 in the morning is 1741 (16%). This represents the highest risk. 5683 in the afternoon is 53%. 1315 Between September 13-24, 2001, 174 (1.5%) is the lowest.
They are monitored up to death or December 31, 2016, depending on when they die. Then, their cancer risk is compared with that of American men. The World Trade Center firefighters had approximately 915 cancer cases, while the 909 firefighters had 1,002 cancer cases.
The World Trade Center firefighters are more likely to develop cancer than their colleagues who don’t work on the spot. This is due to the possibility of influencing factors such as smoking and military service. Their risk of developing prostate cancer and thyroid cancer is three times higher than theirs.
Additionally, firefighters at the World Trade Center were 4 years older than their peers when they were diagnosed. They also often had untransmitted diseases that were caught early.
Comparing the incidence of cancer in firefighters to the American male population revealed that both groups had higher rates of skin and prostate cancer.
These differences can be reduced when we consider the “monitoring biased”, which means firefighters will be able to detect more cancer cases since their health will have been closely monitored.
The World Trade Center may partly be responsible for the high risk of prostate cancer. Some chemicals that are commonly found on construction sites (PCBs, building blocks, etc.) have been shown to affect androgen metabolism. Endocrine disruptors,” the researchers pointed out.
They added that the high incidence of certain types of cancers, including thyroid cancer and prostate cancer, could be caused by non-biological factors such as participation in screening programs related to the World Trade Center.
This observational study cannot determine the cause. The researchers concluded: “Twenty years after the 9/11 incident, to have a clearer understanding of the risks associated with the World Trade Center, monitoring and modeling studies (laboratory or animal-based) need to be expanded to determine all firefighters’ jobs The exposure at the scene.”
