New Study Suggests Link Between ‘Forever Chemicals’ and Thyroid Cancer Risk
A recent study conducted by doctors from Mount Sinai hospital in New York has found a potential link between certain chemicals known as PFAS, or ‘forever chemicals’, and an increased risk of thyroid cancer. The study, which analyzed data from patients with thyroid cancer, discovered that these individuals were 56 percent more likely to have elevated levels of PFAS chemicals in their system.
PFAS chemicals, also known as per- and polyfluoroalkyl substances, are virtually impossible for the body to break down and have been used in the manufacturing of everyday products since the 1940s. They can be found in items such as clothing, carpeting, and food packaging, and have gained attention due to their persistence in the environment and potential health risks.
The researchers focused on a specific PFAS chemical called n-PFOS, which has been commonly found in various consumer products. The study revealed that as the levels of PFAS in blood samples doubled, the risk of being diagnosed with thyroid cancer increased by 56 percent. These findings suggest that these chemicals disrupt the function of the endocrine system, including the thyroid gland, and contribute to the growth and replication of cancer cells.
Thyroid cancer cases have been on the rise, with a staggering 240 percent increase between 1973 and 2002. While improved diagnostic abilities likely contribute to this trend, the study adds to a growing body of research that points to the potential role of PFAS chemicals. Previous studies have shown links between thyroid problems and PFAS exposure, particularly in pregnant women and their unborn babies.
Thyroid cancer affects the gland in the neck responsible for regulating important bodily functions such as metabolism, heart rate, blood pressure, and temperature. Approximately 44,000 Americans are expected to be diagnosed with thyroid cancer this year, according to estimates. However, early detection leads to a high survival rate of around 98 percent.
The widespread use of PFAS chemicals in numerous products, ranging from raincoats and cookware to firefighting foam and food packaging, has raised concerns about their toxicity. Furthermore, PFAS contamination has been found in drinking water supplies across the United States due to contaminated runoff and the widespread use of pesticides.
What compounds these concerns is evidence suggesting that manufacturers were aware of the risks associated with PFAS chemicals since the 1960s but failed to disclose them. The study underscores the urgent need to reduce and eliminate exposure to PFAS chemicals in order to prevent potential health risks.
As scientists continue to unravel the impact of ‘forever chemicals’ on human health, individuals are encouraged to seek out products that are free from PFAS or engage in measures to minimize exposure. With increasing awareness, a concerted effort can be made to protect public health and mitigate the risks associated with these persistent chemicals.
