Link Between Hashimoto's Disease and Cancer
Hashimoto’s thyroiditis (also called Hashimoto’s disease) is an autoimmune disease the is caused by the body’s immune system attacking the thyroid gland. Having Hashimoto's thyroiditis may increase the risk of certain cancers, specifically thyroid cancer. The level of increased risk for thyroid cancer in individuals with Hashimoto's thyroiditis is significantly higher compared to those without the condition. However, it's important to note that the overall risk of developing thyroid cancer is still relatively low.
Other variables that can further increase the risk of developing thyroid cancer include:
- Genetic factors: Certain genetic conditions like Cowden syndrome and familial adenomatous polyposis can increase the chance of developing thyroid cancer.
- Radiation exposure: Previous exposure to radiation, especially during childhood, can increase the risk of developing thyroid cancer.
- Lack of iodine: A diet low in iodine may also increase the risk of developing thyroid cancer, although this is less likely in areas where iodine is added to table salt.
It's worth mentioning that while there may be a slight increase in the risk of stomach and anal cancers among individuals with hypothyroidism (which can be caused by Hashimoto's), these associations are not as strong or well-established as the link between Hashimoto's and thyroid cancer.
It's always a good idea to discuss your individual risk factors and concerns with your healthcare professional, who can provide personalized advice based on your specific situation.
