Firefighters are known for their courage and commitment to protecting lives and property. However, their heroic efforts often expose them to numerous hazards, including toxic substances. One such substance is Aqueous Film-Forming Foam (AFFF), commonly used in firefighting operations.
While AFFF has been instrumental in suppressing flammable liquid fires, emerging evidence suggests a link between AFFF exposure and various types of cancer.
In this article, we will explore the potential health risks associated with AFFF fire fighting foam and the importance of raising awareness among firefighters and the general public.
Understanding AFFF and its Use
Aqueous Film-Forming Foam (AFFF) is a firefighting agent primarily used to extinguish fires involving flammable liquids such as petroleum, oil, and gasoline. It consists of a mixture of synthetic chemicals known as per- and polyfluoroalkyl substances (PFAS).
PFAS are a large group of man-made chemicals that are resistant to heat, oil, water, and stains, making them highly effective in forming a film on the liquid surface to suppress fires.
Cancer Risks Associated with AFFF Exposure
While AFFF has been widely used for decades, concerns have arisen about its potential health effects due to the presence of PFAS. Numerous studies and scientific research have shown that exposure to PFAS chemicals, including those found in AFFF, may increase the risk of several types of cancer.
In light of these findings, an AFFF lawsuit has been initiated, with individuals who believe they have suffered adverse health effects from these compounds suing the manufacturers as noted TruLaw.
The plaintiffs claim that the manufacturers failed to disclose adequate safety information. The AFFF lawsuit is presently underway, and law firms are actively accepting new clients on a daily basis. As of June 16, a total of 4,793 cases have been filed in connection with the AFFF lawsuit.
The following are some of the cancers associated with AFFF exposure:
Testicular Cancer
Studies conducted on laboratory animals have shown that the administration of large doses of PFAS chemicals leads to the development of malignant tumors. While a significant portion of the American population, up to 97%, carries these hazardous chemicals in their bloodstream, firefighters have even higher concentrations, putting them at a heightened risk of developing testicular cancer.
Testicular cancer is a major cause of death among both military and civilian firefighters, with the use of AFFF fire fighting foam being a significant contributing factor. Experts suspect that exposure to PFAS chemicals during fetal development may explain why testicular cancer is commonly seen in young adults.
The rapid increase in cancer rates suggests an environmental cause. A study published in the Journal of Clinical Endocrinology and Metabolism found that young men exposed to high levels of PFAS over extended periods often experience reproductive system issues, such as reduced testosterone activity, resulting in smaller genitalia and lower sperm counts.
Early diagnosis of testicular cancer is crucial for successful treatment, but misdiagnosis can hinder effective treatment. Common symptoms include painless lumps or enlargements in the testicles.
Since testicular cancer caused AFFF exposure has a latency period of around 15 years, it is important for urologists to conduct thorough examinations and estimate current PFAS serum levels and establish potential links between exposure levels and testicular cancer.
Kidney Cancer
In December 2021, a lawsuit was filed in a federal court in South Carolina, claiming that a Florida man developed kidney cancer due to exposure to firefighting foam. The man had been exposed to the foam while extinguishing fires and undergoing training throughout his career as a firefighter.
Scientists and health professionals have increasingly reported that exposure to PFAS chemicals may adversely affect kidney function. Several studies conducted on workers exposed to high levels of PFOA have revealed a link between PFOA and kidney cancer.
Furthermore, evidence suggests that PFAS exposure may also be associated with poorer overall kidney health in humans, indicated a lower estimated glomerular filtration rate and a higher prevalence of chronic kidney disease. It is important to note that kidney cancer often does not cause noticeable symptoms in its early stages.
Additionally, the study highlights that exposure to PFOA and PFOS (another type of PFAS) increases the risk of developing kidney cancer 50%.
Bladder Cancer
According to the American Cancer Society, bladder cancer was expected to result in 17,100 deaths the end of 2022, making it the fourth most common cancer among men. Over 81,000 individuals are expected to receive a bladder cancer diagnosis during the same period, including a significant number of firefighters.
Firefighters face a 9% higher risk of developing cancer, and the use of AFFF firefighting foam significantly contributes to this concerning statistic. Recent medical studies suggest that exposure to PFAS chemicals can lead to changes in bladder tissue cells, potentially increasing the risk of bladder cancer. Firefighters, due to their exposure to PFAS, have a higher risk of bladder cancer compared to the national average.
Breast Cancer
Breast cancer, the most common malignant disease among women in the United States, affected over 287,000 women the end of 2022. While the well-known BRCA1 and BRCA2 gene mutations are risk factors, exposure to perfluoroalkyl and poly-fluoroalkyl substances (PFAS) from AFFF firefighting foam is a lesser-known factor, particularly for female firefighters.
Surprisingly, nearly 28% of women in civilian or military firefighting roles develop breast cancer. A recent study in the journal Toxics suggests a link between PFAS exposure and breast cancer. Analyzing data from eight studies, the research found a strong correlation between breast cancer risk and exposure to PFOA, a common PFAS chemical.
Additionally, six studies showed a positive correlation with PFHxS. Even low levels of PFAS exposure can alter the structure and growth of mammary glands, increasing breast cancer risk, as indicated research from the Environmental Working Group.
Conclusion
The use of AFFF firefighting foam has undoubtedly played a vital role in preventing and extinguishing flammable liquid fires. However, emerging evidence suggests a potential link between AFFF exposure and various types of cancer.
Understanding the associated health risks and taking proactive measures to mitigate exposure is crucial for the well-being of firefighters and all those involved in firefighting operations. By raising awareness, implementing safety measures, and supporting ongoing research, we can work towards a safer future in firefighting without compromising the health of our brave firefighters.
