Are “Forever Chemicals” Forever a Risk to Thyroid Health?
Connection Found Between PFAS Forever Chemicals and Elevated Risk of Thyroid Cancer
PFAS chemicals linked to higher thyroid cancer risk
Researchers have discovered a connection between certain chemicals found in common household items and an increased risk of thyroid cancer. In a new study published in the Lancet journal eBioMedicine, it was reported that people exposed to per- and polyfluoroalkyl substances (PFAS) had a 56% higher chance of developing thyroid cancer. These “forever chemicals” can be found in products such as nonstick cookware, water-repellent clothing, and stain-resistant fabrics. Unfortunately, exposure to PFAS is widespread and difficult to avoid.
The study compared 88 individuals with thyroid cancer to a control group of 88 people without the disease. The researchers found that exposure to a specific type of PFAS, called perfluorooctanesulfonic acid (n-PFOS), increased the risk of thyroid cancer by 56%. Additionally, they identified an association between the disease and several other PFAS chemicals. These findings provide further evidence of the PFAS health crisis and emphasize the need to reduce exposure to these chemicals.
PFAS are known as “forever chemicals” because they do not easily break down and can be found in soil, water, and air. They have been used since the 1940s, making their potential risks even more concerning. The chemicals are classified as endocrine disruptors, meaning they can affect the body’s hormone-producing glands, including the thyroid gland.
So, how do PFAS chemicals increase the risk of thyroid cancer? Exposure to PFAS can alter the levels and actions of thyroid hormones, leading to dysfunction or disease in the thyroid. These chemicals can accumulate in the thyroid gland, affecting its structure and function. Studies have shown that PFAS induce oxidative stress, inflammation, cell death, and DNA damage in thyroid tissue, ultimately increasing the risk of cancer. PFAS may also impact the immune system’s ability to detect and eliminate thyroid cancer cells.
To reduce exposure to PFAS, consider using activated carbon filters or reverse osmosis systems for drinking water if you live in an area with contamination. Limit the use of nonstick cookware, grease-resistant food packaging, and stain-resistant treated clothing. These small changes can make a big difference in reducing your exposure to these harmful chemicals.

While this study sheds light on the connection between PFAS and thyroid cancer, there is still much to learn. Researchers are continuing to investigate other chemicals and metabolites associated with thyroid cancer and the potential impact of PFAS exposure on populations with high exposure, such as the U.S. military.
The findings from this study highlight the severity of the “forever chemicals” crisis. It’s crucial to raise awareness and advocate for industry changes to eliminate PFAS altogether. Everyone should discuss their PFAS exposure with their healthcare provider to determine their risk and consider appropriate screenings. Let’s work together to protect our thyroid health and create a safer environment for all.
