What the science says about PFAS / AFFF firefighting foam
PFAS (per- and polyfluoroalkyl substances) are a family of man-made chemicals that persist in the body for years. In the military the dominant source is AFFF (aqueous film-forming foam), the firefighting foam used for decades in crash crews, shipboard firefighting, and fire-training pits, plus contaminated drinking water on and around bases. Exposure is by skin contact with foam and by drinking contaminated water.
Health effects documented in the toxicology literature:
- Kidney and testicular cancer: The strongest cancer evidence is for kidney (renal-cell) and testicular cancer, chiefly tied to PFOA, one of the main PFAS in older AFFF.
- Thyroid: Associated with thyroid disease and altered thyroid hormone levels.
- Liver / cholesterol: Raises cholesterol and liver enzymes; evidence of liver effects.
- Immune system: Reduced antibody response to vaccines; evidence of decreased infection resistance.
- Pregnancy: Associated with pregnancy-induced hypertension and pre-eclampsia.
Cancer classification: IARC (2023): PFOA Group 1 (carcinogenic to humans); PFOS Group 2B (possibly carcinogenic).
Latency: PFAS have half-lives of years in the human body, so blood levels, and disease risk, can persist long after the exposure ends; cancers can appear years to decades later.

Common questions
Is PFAS / AFFF firefighting foam a presumptive exposure?
No. Unlike Agent Orange, burn pits, or Camp Lejeune, PFAS / AFFF firefighting foam carries no automatic (presumptive) service connection. You have to prove the medical link yourself, usually with a nexus opinion, which is exactly why how the Board has ruled on it matters.
Why do so many of these conditions show denials?
The granted / denied counts reflect the mix of cases where PFAS / AFFF firefighting foam comes up and how hard each link is to prove, not the merit of any one claim. A denial often means the file lacked a medical opinion tying the condition to the exposure, or proof of the exposure itself, not that the condition can never be connected.
How do I show I was exposed to PFAS / AFFF firefighting foam?
Service records, your military job (MOS), unit history, and buddy statements can establish the exposure; a medical opinion then connects it to the diagnosed condition. This page reports Board outcomes and is not legal or medical advice, a VSO representative can help with your specific case.
