Causes and Warning Signs of Thyroid Cancer
Thyroid cancer is a rare type of cancer affecting the thyroid gland, a gland situated at the base of the neck. The cause of the disease may not be known at the initial stages, but some environmental and genetic factors may lead to the onset. Some people may have the symptoms early on, while some may experience none. Therefore, it is crucial to be aware of the silent warning signs to avail of timely diagnosis and treatment. Causes of thyroid cancer Unregulated cell growth When cells in the thyroid grow and divide at an abnormally fast rate, it can lead to the development of thyroid cancer. Genetic mutation Sometimes, a mutation in a gene can cause it to become faulty, leading to a higher risk of developing thyroid cancer. Radiation exposure Exposure to high doses of radiation, such as radiotherapy treatment, may increase the risk of developing thyroid cancer. Age Thyroid cancer is more common in people over age 45. Certain health conditions People with certain autoimmune disorders, such as Hashimoto’s and Graves’ disease, may be more likely to develop thyroid cancer. Additionally, those with goiter (enlargement of the thyroid gland) or those who have previously been exposed to therapeutic levels of iodine (such as those undergoing health imaging procedures) may also be more prone to developing thyroid cancer.
