How is thyroid cancer caused

How is thyroid cancer caused? Thyroid cancer is a malignant tumor of the thyroid gland, and its mortality rate ranks second among cancer mortality rates. Among them, the probability of women suffering from thyroid cancer is 3 times higher than that of men, which seriously affects the patient's physical and mental health, and also affects their lives. So, how is thyroid cancer caused?

1. Iodine intake: Clinically, iodine is the raw material for synthesizing thyroid hormones, and iodine intake is closely related to thyroid disease. Surveys show that there is a "U" relationship between iodine intake and the incidence of thyroid disease, that is, too low or too high iodine intake will lead to thyroid disease.

2. Genetic factors: Thyroid cancer has obvious familial inheritance. About 7% of medullary thyroid cancer has a clear family history, and is often combined with pheochromocytoma, etc. It is speculated that the occurrence of this type of cancer may be related to chromosomal genetic factors.

3. Radiation damage: Studies have shown that exposure to radioactive substances in the head and neck is an important factor in causing thyroid cancer. For example, electrical appliances and CT scans that we come into contact with in daily life will increase the incidence of thyroid cancer. In addition, the incidence of thyroid cancer in women who are exposed to ionizing radiation such as X-rays and CT scans is significantly increased.

4. Female estrogen level: The incidence of thyroid cancer in women is significantly higher than that in men, with a male-female ratio of 1:3. As for why the incidence in women is higher, this may be related to the female estrogen level. In addition, the increase in the incidence of thyroid cancer may also be related to the popularization of color Doppler ultrasound technology, the improvement of the examination level of ultrasound doctors, and the improvement of the accuracy and sensitivity of the instrument.

It is difficult to have clear regulations on iodine intake in the diet, as long as the nutrition is balanced. In addition, low selenium may also lead to thyroid cancer. Therefore, you should eat more selenium-rich foods, such as fish, shrimp, crab, sesame, garlic, etc. At the same time, try not to come into contact with radioactive sources, and be more cautious when doing radioactive treatment.
