AFFF and testicular cancer

The PFAS in AFFF foam are man-made chemicals that don't break down quickly, either in your body or in the world around you. Two members of that family, PFOA and PFOS, have drawn the most cancer research.

A court put together a team of scientists, the C8 Science Panel, to study people living close to a DuPont plant. Its April 16, 2012 report said PFOA was probably linked to both testicular cancer and kidney cancer, while finding no probable link for the other cancers it reviewed. The panel filed its report with the Wood County, West Virginia, court (C8 Science Panel). "Probable link" is a legal term. It says the exposure and the illness are more likely connected than not. It doesn't prove one caused the other.

Then, in July 2023, a federal study appeared. It compared stored blood from 530 U.S. Air Force servicemen diagnosed with testicular cancer against blood from 530 similar men without the disease (PubMed). Firefighters in the military carried more of several PFAS in their blood, among them PFOS, PFHxS and PFOA. Men in the top quarter for PFOS had roughly 2.6 times the odds of a testicular germ cell tumor as those in the bottom quarter. PFOS was the only chemical in that study connected to higher risk. The study found no link between the other PFAS it looked at and testicular cancer (National Cancer Institute).

That November, the cancer agency of the World Health Organization graded the chemicals one by one. PFOA went into its top group, carcinogenic to humans, pointing to human evidence for kidney and testicular cancer, though that evidence was limited. PFOS ended up lower, in a group for possible carcinogens, because the agency judged the human evidence inadequate (Science Direct). Firefighting as a job also sits in the top group, though the evidence that it leads to testicular cancer was rated only limited (Occupational Cancer Research Centre).

There's one more figure to know. A study of Ontario firefighters found their testicular cancer risk ran 156% higher than other workers, and it flagged the PFOA in firefighting foam as one possible contributor (Occupational Cancer Research Centre).

It is. In December 2018 the federal AFFF cases were all pulled into one courtroom, the federal district court in South Carolina. Of the 4 diseases picked for the first round of personal injury test cases, testicular cancer is one (Harris Beach Murtha). A test case like this, called a bellwether, goes to trial before the thousands of other cases move forward so both sides can watch how a jury reacts. The claims in that first round involve PFAS from AFFF in drinking water.

Judge Richard M. Gergel runs the combined case, which has drawn more than 10,000 cases since it started (U.S. District Court, District of South Carolina). About 15,264 cases were still open as of October 2026 (Drugwatch).

People with cancer and other personal injuries are still waiting on a settlement. A mediator is continuing the settlement talks under court orders (MDL Update). Settlements worth over $13 billion have been approved, but all of that money went to public water systems. It has nothing to do with injury claims by individuals (Harris Beach Murtha).

The first injury trial, involving kidney cancer, was set for October 2025 but never happened. By late June 2026, no new trial date was on the calendar (Lawsuit Information Center). Meanwhile, the court is preparing a second test group, this one covering thyroid disease and ulcerative colitis, and proposals on it are due November 20, 2026 (MDL Update).

A couple of other developments matter if you're thinking about filing. A court order opened a 3-week window for new cases, which shut on September 5, 2025, and anything filed after that date has to clear extra hurdles (ELG Law). Margaret Seymour was named special master in June 2026 to handle motions to dismiss, and the judge expects defendants to move to dismiss around 8,000 lawsuits (Robert King Law Firm). A few law firms have stopped accepting new AFFF claims. TorHoerman Law shut its intake in October 2026 (TorHoerman Law).

In a lot of states, yes, and this path runs separately from the federal case. Out of 50 states, 41 have a firefighter cancer presumption on the books. That's a law treating certain cancers as job-related unless the employer shows otherwise (IAFF). Testicular cancer is listed by name in 25 of those laws. Another 15 states cover it when it can be tied to the firefighter's exposure.

Arizona, Colorado, Connecticut, Florida, Idaho, Iowa, Louisiana and Maine are among the states that name it. So are Maryland, Michigan, Missouri, Montana, Nevada, New Mexico and New York. The others are Oregon, Rhode Island, Tennessee, Texas, Utah, Vermont, Virginia, Washington, West Virginia and Wisconsin. You can check your own state's rule on the home page checker or on its state page.

Presumption laws aren't universal. Delaware, Georgia, Mississippi and South Carolina give firefighters insurance money for cancer instead of presuming anything. Arkansas, Kentucky and North Carolina provide a benefit only for line-of-duty deaths. South Dakota limits its rule to pensions. Hawaii has no cancer rule at all, just one for lung disease (IAFF). Federal firefighters fall under federal law, which lists 14 cancers, testicular cancer among them, and asks that firefighters have served at least 5 years (IAFF).

If you're filing a testicular cancer claim, your clock normally starts the day you get the diagnosis, not the date you were exposed to the foam (TruLaw). That's important, since exposure could go back years or decades. Deadlines vary by state and some firms have stopped taking new cases, so check your state's page and call the claims line sooner rather than later.
