Firefighters, military service members, and airport crews used AFFF firefighting foam for decades to knock down fuel fires, often without knowing it contained PFAS chemicals.
Federal health regulators now say one of those chemicals, PFOA, is likely to cause cancer in humans, and testicular cancer is one of the specific cancers they point to. That’s an important finding, but it isn’t the same as proving that AFFF caused any one person’s cancer.
A real evaluation depends on your documented exposure, your diagnosis, and expert medical evidence connecting the two.
Prior results do not guarantee a similar outcome.
What Is AFFF and Why Does It Contain PFAS
Aqueous film-forming foam, or AFFF, is a Class B foam built to smother fuel and other flammable-liquid fires. It was the standard tool at military bases, airports, refineries, fire academies, and municipal fire departments for decades.
Many older formulations relied on PFAS chemicals, including PFOA and PFOS, to create the film that spreads across burning fuel and cuts it off from oxygen.
PFAS are often called “forever chemicals” because they resist breaking down in soil, groundwater, and the human body. Once someone is exposed, whether through skin contact, inhaling airborne particles during foam application, or drinking contaminated water, these chemicals can stay in the bloodstream for years.
What Does the Science Say About PFOA and Testicular Cancer
In April 2024, the EPA published its final human health toxicity assessment for PFOA, reviewing more than 780 human and animal studies. The agency concluded that PFOA is likely to be carcinogenic to humans by the oral route of exposure, and it specifically identified kidney and testicular cancer in adults as the human cancer outcomes supporting that conclusion, alongside testicular, pancreatic, and liver tumors observed in animal studies. (EPA, Human Health Toxicity Assessment for PFOA)
The International Agency for Research on Cancer reached a related conclusion in its own 2023 review, classifying PFOA as carcinogenic to humans, based on limited evidence in humans for kidney and testicular cancer combined with sufficient evidence in animal studies and strong mechanistic evidence.
This isn’t a new concern. Years earlier, the C8 Science Panel, which studied a community near a DuPont plant in the Mid-Ohio Valley with PFOA-contaminated water, found a probable link between PFOA exposure and both kidney and testicular cancer. EPA’s 2024 assessment builds on that earlier work with a much larger body of evidence.
It matters to be precise about what this science does and doesn’t show. These findings describe an association across populations, not a guarantee for any specific person.
A positive association means people with higher documented PFOA exposure had somewhat higher rates of testicular cancer in the studies reviewed, not that PFOA exposure explains every case, or that a person’s blood test result alone tells you when or where their exposure happened.
Who Is at Risk for AFFF-Related PFAS Exposure
The people with the clearest exposure history to AFFF-related PFAS generally fall into a few groups.
Firefighters and airport rescue personnel who mixed, sprayed, trained with, or cleaned up AFFF regularly over years of service.
Military service members, veterans, and civilian defense workers stationed at bases where AFFF was used for fire training or emergency response.
Workers who maintained fire-suppression systems, hangars, or fuel storage facilities where foam concentrate was stored or dispensed.
Residents and workers who drank water drawn from a source affected by AFFF runoff near a training site, airport, or military installation.
A single, brief, incidental contact with AFFF looks very different, evidentially, than years of regular occupational handling or a documented history of drinking contaminated water. It’s also worth remembering that PFAS exposure isn’t limited to AFFF.
These chemicals also show up in some consumer products, packaging, and industrial releases, so a PFAS blood test alone doesn’t tell you the source of your exposure.
Testicular Cancer Symptoms and Risk Factors to Know
The American Cancer Society estimates about 9,810 new testicular cancer diagnoses and about 630 deaths from the disease in the United States in 2026. A man’s lifetime risk of developing it is about 1 in 250, and the average age at diagnosis is 33, making it primarily a disease of young and middle-aged men.
Because it’s usually highly treatable, especially caught early, the lifetime risk of dying from it is much lower, around 1 in 5,000. (American Cancer Society, Key Statistics for Testicular Cancer)
Recognized risk factors include an undescended testicle, a personal or family history of testicular cancer, and certain genetic conditions.
The cause of most individual cases remains unknown, which is exactly why a documented AFFF exposure history and a qualified medical opinion matter so much in evaluating a specific case rather than assuming a straight line from exposure to diagnosis.
Symptoms worth prompt medical evaluation include a painless lump or swelling in a testicle, heaviness or aching in the scrotum or lower abdomen, or a sudden buildup of fluid in the scrotum. Don’t wait to have a change checked out, and don’t try to self-diagnose based on what you read online.
Can You Sue for Testicular Cancer Linked to AFFF Exposure
Yes, Thousands of firefighters and veterans have filed claims alleging AFFF exposure caused their testicular cancer, and courts have recognized testicular cancer as one of the categories of injury being litigated in the coordinated federal AFFF proceeding centered in South Carolina.
These cases generally argue that manufacturers knew or should have known about PFAS health risks and failed to warn the people using their product.
Because the litigation and the underlying science are both still developing, be wary of anyone who tells you exactly what your case is worth before reviewing your specific records. No standard payout structure exists for these claims.
What Are New York’s Rules on PFAS Firefighting Foam
New York has restricted PFAS-containing Class B firefighting foam, including AFFF, under General Business Law § 391-u. Since March 22, 2022, manufacturers generally cannot manufacture, sell, or distribute firefighting foam with intentionally added PFAS in New York, and discharging that foam during training is prohibited outright.
The law carves out an exception where federal law or regulation requires a PFAS-containing foam, which is why some military and civilian aviation facilities have continued using it for actual fires.
New York has also moved to address the equipment side of the problem. State law now bars manufacturers from selling firefighter turnout gear with intentionally added PFAS chemicals, effective January 1, 2028, on top of the existing restrictions on the foam itself.
What Are New York’s Deadlines for an AFFF Claim
New York’s discovery rule for latent exposure injuries, CPLR 214-c, generally gives you three years from the date you discovered your injury, or reasonably should have, to file a personal injury claim, rather than three years from the date of exposure itself.
Because AFFF exposure often happened years or decades before a testicular cancer diagnosis, this discovery-based timing is usually what protects your ability to bring a claim at all.
Deadlines can shift depending on the specific defendants and legal theory involved, so don’t assume you’ve missed your window just because your exposure happened a long time ago.
Why Getting the Evidence Right Matters
A testicular cancer diagnosis is stressful enough without also trying to sort out which parts of the AFFF science are settled and which parts are still being litigated.
Porter Law Group works with medical and toxicology experts to build the exposure and causation record these product liability claims require, rather than relying on general statements about PFAS and cancer.
Porter Law Group has recovered more than $500 million for injured clients across New York. Prior results do not guarantee a similar outcome.
Frequently Asked Questions
Does having elevated PFAS in my blood mean AFFF caused my testicular cancer?
Not by itself. A blood test can show that you were exposed to certain PFAS chemicals, but it generally can’t tell you when the exposure happened, where it came from, or whether it caused your specific cancer. Blood test results are usually one piece of a larger case built from your work history, service records, and medical evidence, not standalone proof of causation.
I was only briefly exposed to AFFF during training. Do I still have a case?
It depends on the documentation available. Cases with years of regular occupational AFFF use tend to have stronger exposure evidence than a single brief training exercise, but every situation is different. What matters most is whether you can document the exposure and connect it to your diagnosis through medical and expert evidence, not simply how the exposure happened.
How long do I have to file a claim if I was exposed to AFFF decades ago?
New York generally allows three years from the date you discovered your injury, or reasonably should have, rather than three years from your original exposure. Because testicular cancer can develop long after AFFF exposure occurred, many people are still within their filing window even if the exposure itself happened years ago. The specific deadline can depend on who you’re pursuing a claim against, so it’s worth having your timeline reviewed.
Does New York’s ban on PFAS firefighting foam mean I can’t have been exposed recently?
No. New York’s restriction on manufacturing, selling, and training with PFAS-containing foam took effect in March 2022, and it includes an exception for uses required by federal law, which has kept some AFFF in use at certain military and aviation facilities. If you were exposed before 2022, through a federal exception, or through legacy contamination in soil or water from years of past use, that exposure remains relevant regardless of the current law.
Is testicular cancer treated as a presumptive condition for PFAS-exposed veterans?
Not currently. The VA’s active PFAS presumption review, launched in 2024, is evaluating kidney cancer, not testicular cancer. That means a veteran with testicular cancer generally still needs to establish an individual service connection rather than relying on an automatic presumption. This is worth confirming directly with the VA, since presumptive condition lists can change.
