What are the triggering factors of thyroid cancer? Five common causes of thyroid cancer

The main risk factors of thyroid cancer include: radiation exposure, genetic factors, disease factors, abnormal iodine intake, abnormal estrogen levels, etc.

1. Radioactive exposure

Exposure to radiation on the head or neck in infancy can easily induce thyroid cancer, but it is less common in adults.

2. Genetic factors

The incidence of thyroid cancer is related to genetic factors. Nearly 25% of medullary thyroid cancer has a familial hereditary tendency, and those with a family history of thyroid cancer have a higher incidence rate.

3. Disease factors

Familial multiple polyps, hypothyroidism or hyperthyroidism are also common causes of thyroid cancer.

4. Abnormal iodine intake

Excessive or insufficient iodine intake will affect the normal function of the thyroid gland. When the thyroid function is affected, the risk of cancer will increase significantly.

5. Abnormal estrogen levels

If the abnormal levels of estrogen and progesterone are not corrected in time, it will not only induce endocrine disorders but also easily lead to thyroid cancer.
