Risk factor 15. Certain Occupational and Environmental Exposures
Last but not least, certain occupational and environmental exposures can also elevate the risk of thyroid cancer. Exposure to radiation, as previously mentioned, is a significant risk factor. However, exposure to some chemical substances, particularly in specific occupational settings, can also increase risk.
For instance, studies suggest that exposure to asbestos, a common industrial material, is associated with a higher risk of thyroid cancer. The exact mechanisms behind this association are not fully understood, but it’s thought that asbestos fibers, when inhaled, can trigger inflammation and DNA damage, potentially leading to cancer.
Additionally, exposure to certain heavy metals and pesticides has been linked to an increased risk of thyroid cancer. Workers in industries such as mining, agriculture, and chemical manufacturing may have a higher exposure to these substances and, therefore, a potentially elevated risk.
On the environmental side, exposure to radon, a naturally occurring radioactive gas, has been associated with an increased risk of thyroid cancer. Radon exposure typically occurs through inhalation in homes built on soil with high radon levels.
Closing this section, it’s crucial to remember that while occupational and environmental exposures can increase thyroid cancer risk, these risks often interact with other factors, including individual genetic makeup and lifestyle factors. Therefore, efforts to minimize exposure, combined with regular health checks, particularly for those in high-risk occupations, are key strategies in managing this risk factor. (15)
