The thyroid gland is an endocrine gland located in front of the laryngeal knot and consists of two lateral and narrow lobes on the left and right, resembling a butterfly.
The secretion of thyroxine and calcitonin plays a vital role in regulating the body's metabolic balance.
Thyroid cancer is a malignant tumor that occurs in the thyroid gland, accounting for about 1% of cancer, which is extremely harmful to human health.
According to its pathological type, thyroid cancer is clinically divided into four types, namely papillary carcinoma, foamy thyroid cancer, medullary thyroid cancer, and undifferentiated thyroid cancer.
Among them, papillary carcinoma is the most common, accounting for 80%, while thyroid undifferentiated carcinoma is very rare.
In the early stage of thyroid cancer, most of them do not cause obvious physical discomfort, but with the development of the disease, patients may have symptoms such as local swelling and pain, difficulty swallowing, hoarseness, diarrhea and palpitations.
Therefore, when these symptoms appear, they must pay attention to it and treat them in a timely manner according to the specific cause. So what are the causes of thyroid?
1. Familial inheritance
Thyroid cancer has a certain hereditary nature. Data have shown that people with a history of thyroid cancer in their families are also more likely to develop thyroid cancer than others.
Therefore, such people need to take more precautions every day, and it is best to go to the hospital regularly for relevant examinations.
In particular, when there is discomfort in the thyroid area, it is necessary to be vigilant, find out the specific cause, and give symptomatic treatment.
2. Age and hormonal changes
Thyroid cancer is more common in adults, with the highest proportion of patients between the ages of thirty and fifty, and mostly female cases.
This is because tumors are mostly formed on the basis of proto-oncogene mutations, and it takes years or decades to develop from proto-oncogene mutations to tumors that can be seen with the naked eye or can be detected by imaging.
It is precisely because of this that many cancers will appear in middle-aged and elderly people. Second, hormonal changes can also lead to thyroid cancer.
If there is a hormonal imbalance, thyroid nodules may form, and if it worsens, there is a certain chance of inducing thyroid cancer.
3. Radiation linear damage
If you are often exposed to radioactive substances, the probability of developing thyroid cancer will be higher than that of ordinary people, such as the staff of the CT room.
In such a working environment for a long time, if there is no protective measures, it may lead to the normal secretion of thyroxine, which will promote cancerous thyroid gland.
Therefore, in order to be healthy, we must stay as far away from objects and environments containing radiation as possible in life to reduce radiation linear damage.
4. Unreasonable diet
A reasonable diet can keep people healthy. However, at the current pace of life, many people are unable to achieve a reasonable and scientific diet.
In the long run, it may lead to a lack of iodine in the body, affect thyroid health, and increase the potential risk of thyroid cancer.
Lack of iodine is certainly not good for the body, but if too much intake can also damage the thyroid gland, and even induce thyroid papillary carcinoma.
Although the thyroid gland is a very important part of the human body, it rarely receives attention.
The thyroid gland is actually very fragile, and if damaged, thyroid nodules may occur at mild, and cancer may occur in severe cases.
Therefore, everyone should do the corresponding protection according to the above inducements to reduce the possibility of disease. If the diagnosis is confirmed, it must be treated promptly to minimize the damage as much as possible.
