What are the causes of thyroid cancer? These 4 points are the main causes of thyroid cancer

One of the causes of thyroid cancer is heredity. If someone in the family has thyroid cancer, the chances of other immediate family members getting the disease will increase. Ionizing radiation and iodine deficiency are also common causes of thyroid cancer. In addition, if you have other thyroid diseases and the condition is not treated promptly and effectively, the chances of developing thyroid cancer will increase.

Thyroid cancer is a malignant disease that occurs in the thyroid gland and can seriously affect the function of the thyroid gland. If not treated in time, cancer cells may metastasize to distant sites, endangering the patient's life. To treat thyroid cancer, the key is to first identify its specific cause. So what are the causes of thyroid cancer?

1. Genetic factors

Genetic factors are one of the common causes of thyroid cancer. According to relevant survey data, among many thyroid cancer patients, 3-5% are caused by genetics. If a direct relative in the family has thyroid cancer, the probability of the offspring getting the disease will be higher than that of ordinary people. The closer the blood relationship, the higher the incidence rate.

2. Ionizing radiation

The incidence of thyroid cancer is also closely related to ionizing radiation. X-rays are a type of radiation that everyone is familiar with, and this type of radiation has strong ionizing radiation. If exposed for a long time, it will cause mutations in human cell genes, and the growth rate of mutated cancer cells will be very fast. Moreover, this type of radiation will kill some normal cells, providing an opportunity for the growth of cancer cells. In addition, if you are frequently exposed to ionizing radiation, the secretion of thyroid hormones in the body will be significantly reduced, which will promote the continuous deterioration of potential malignant cells and eventually cause cancer.

3. Iodine deficiency

Iodine deficiency is also one of the more common causes of thyroid cancer. Iodine is one of the essential trace elements for the human body. If the body is deficient in iodine, it will easily affect the normal function of the thyroid gland, causing goiter. It will also lead to a significant decrease in the synthesis of thyroid hormones, which will significantly increase the incidence of thyroid cancer.

4. Other thyroid diseases

Other thyroid diseases can easily induce thyroid cancer. Thyroid cancer does not appear all at once. Before it occurs, other thyroid diseases, such as thyroid hyperplasia and hyperthyroidism, usually occur. If you have these thyroid diseases and the condition is not controlled in a timely and effective manner, the cells may become malignant and eventually develop into thyroid cancer.
