Finding: The August 31, 2026 order sets expert-motion dates for thyroid and liver cancer. It does not set an individual payment.

Finding: PFOA is classed as able to cause cancer; PFOS as possibly able to cause cancer. The classifications do not measure individual risk at a given dose.

The process
You answer a few questions
About two minutes. Nothing is sent until you agree on the last step and press submit.
A lawyer looks at it
A lawyer at the firm reads your answers and checks them against the current case criteria.
The firm decides and gets in touch
If the firm takes your case, you get the terms in writing to read before you sign. You can always say no.
Have a thyroid problem and a history with fire foam? Ask your doctor what your tests show. A lawyer can assess a claim without treating disease as cancer.
The thyroid is a gland in your neck. It can make too much or too little hormone. Ask your doctor what problem your record names.
NIDDK describes an underactive thyroid and an overactive thyroid as different conditions. Symptoms, causes and care can differ. A report about hormone levels is not the same as a cancer diagnosis.
Tell your doctor about changes that concern you. Tiredness or weight changes can have many causes. Symptoms alone cannot tell you which thyroid problem you have.
The NIDDK guides describe different signs for low and high thyroid activity. They overlap with signs of other illnesses. Keep symptom dates, but let a clinician interpret them with the exam and test results.
Ask what your blood tests and exam show. Care depends on the cause. Do not change a medicine just to match a lawsuit page.
NIDDK describes history, examination and thyroid blood tests, with imaging in some cases. Neither symptoms nor a PFAS blood level supplies a personal care plan. Discuss benefits and risks with your clinician.
A review found limited evidence of a link with adult thyroid disease. That finding does not prove the cause in your case. It is separate from cancer research.
The 2022 National Academies committee used a category called limited or suggestive evidence of an association. Its thyroid section notes weak or absent links in many newer studies. It does not identify a cause for every patient or brand.
The August 2026 court order concerns expert motions for thyroid and liver cancer. It does not turn a thyroid hormone condition into cancer or announce an individual award.
Have a diagnosis and a possible foam or water exposure? Ask a lawyer which claim, if any, fits. A test result alone does not guarantee acceptance.
Give the exact diagnosis name and exposure history rather than selecting a cancer box for a different disease. PFAS has several possible sources. The relevant product, responsible party and law need review.
Keep thyroid tests, care reports and exposure dates. Ask a lawyer about time limits and costs. Ask your doctor about current care.
Request missing health records from your covered provider. Keep dates for each water source or work task separate from test dates. Before you share files, check the recipient, privacy and written fee terms.
Relative risk of 1.74 for kidney cancer among individuals with high PFAS exposure compared to low-exposure controls
PFAS manufacturers knew about the persistence and toxicity of their products as early as 1970 — more than 50 years before widespread public awareness
Determined "probable link" between PFOA exposure and six diseases: kidney cancer, testicular cancer, thyroid disease, ulcerative colitis, high cholesterol, and pregnancy-induced hypertension
The review is free and private. Asking for it doesn’t commit you to anything.
Register your interestPFAS are potent endocrine disruptors that specifically target the thyroid gland. They interfere with thyroid function through several mechanisms: competing with thyroid hormones (T3 and T4) for binding sites on transport proteins like transthyretin and thyroid-binding globulin; disrupting the hypothalamic-pituitary-thyroid axis that regulates thyroid hormone production; altering the expression of genes involved in thyroid hormone synthesis; and triggering autoimmune responses against thyroid tissue. The C8 Science Panel determined a "probable link" between PFOA and thyroid disease after studying 69,000 exposed residents, and multiple subsequent studies have confirmed the association in firefighters, military personnel, and contaminated communities.
The full spectrum of thyroid disease has been associated with PFAS exposure: hypothyroidism (underactive thyroid, the most common), hyperthyroidism (overactive thyroid), autoimmune thyroiditis (Hashimoto's disease), thyroid nodules, and thyroid cancer (particularly papillary thyroid carcinoma). Hypothyroidism is the most frequently diagnosed thyroid condition in PFAS-exposed populations and causes fatigue, weight gain, cold intolerance, and depression. All of these conditions were encompassed within the C8 Science Panel's "probable link" determination for thyroid disease. If you have been diagnosed with any form of thyroid disease and have a history of AFFF exposure, you may have a viable claim.
No settlement has been announced. What any claim is worth depends on its facts, and no one can promise an amount. Hypothyroidism requires lifelong medication and monitoring, thyroid cancer requires surgery and radioactive iodine treatment, and all thyroid conditions impose ongoing medical costs and quality-of-life impacts. The MDL court is weighing expert evidence on thyroid cancer under an August 31, 2026 order. The C8 Science Panel's "probable link" determination provides the same strong causation foundation for thyroid disease as for kidney or testicular cancer.
