Thyroid cancer: The most common causes
The exact causes of thyroid cancer are still unknown not fully clarified. However, there are certain risk factors that can increase the risk of developing the disease. These are above all
Increased radiation exposure
The thyroid is particularly sensitive to ionizing radiation, which is why increased exposure to radiation, such as one childhood radiation exposure or one medical radiation therapy increases the risk of thyroid cancer. When the thyroid is exposed to ionizing radiation, the DNA and other cell structures in the thyroid cells are damaged become. This, in turn, can cause genetic changes that affect normal cell growth and division, which can lead to cancer.
Genetic predisposition
Genetic predisposition is considered a risk factor for thyroid cancer because certain genetic changes or mutations promote the development of the disease. Various genetic syndromes are associated with an increased risk of thyroid cancer, such as this familial medullary thyroid carcinoma (FMTC)in which a defective gene (RET gene) is inherited from one parent or that multiple endocrine neoplasia syndrome type 2 (MEN2)which is also associated with a genetic change in the RET gene.
Low iodine diet
A diet low in iodine increases the risk of thyroid cancer because iodine is a essential nutrient for the thyroid is. The thyroid needs iodine to produce thyroid hormones. If the body does not receive enough iodine, it can result in thyroid dysfunction.
Iodine deficiency can cause the thyroid to try to absorb more iodine by their cells multiply. This increases the risk of abnormal cell growth and potentially the development of cancer cells. However, iodine deficiency alone is not enough to cause thyroid cancer, as a combination of factors, including genetics and other risk factors, are usually responsible for the development of cancer.

What are the symptoms?
Symptoms of thyroid cancer can vary and often depend on the stage of the disease. Possible signs include:
- Lumps or swelling in the neck area
- difficulties swallowing
- hoarseness
- persistent cough
- enlarged lymph nodes in the neck area
- Pain in the neck or throat
