What is thyroid cancer? What are the common risk factors for thyroid cancer?

Thyroid cancer can cause thyroid enlargement and physical weakness. Genetic factors, radiation damage, irrational iodine intake, sex hormone changes, thyroid disease, and dietary factors can all lead to thyroid cancer. Therefore, if you find that you have thyroid cancer, you should pay great attention to it.

Cancer is a very scary disease. Generally speaking, if you have cancer, you may not live very long, so if you find out that you have cancer, you will be very scared. There are many types of cancer, but the causes of different cancers are different. Let's learn about thyroid cancer.

1. Genetic factors

About 3 to 5 people out of 100 have thyroid cancer due to genetics, so the cause of thyroid cancer may be inherited from parents to children. Of course, further examination and diagnosis are needed.

2. Radiation damage

If you are exposed to radioactive light such as X-rays for a long time, it can easily lead to a decrease in thyroid hormone secretion, leading to cancer. Therefore, radioactive exposure may induce thyroid cancer.

3. Irrational iodine intake

Iodine is an indispensable substance for the human body. If the human body is deficient in iodine, it may cause goiter. It will also affect the synthesis of thyroid hormones and produce a certain stimulation to cells, which will cause cancer. However, if the iodine intake is too much, it will also cause thyroid cancer. Therefore, when taking in iodine, you should not be greedy. A moderate amount is enough, which can reduce the occurrence of thyroid cancer.

4. Changes in sex hormones

Thyroid cancer is generally more common in women than in men, so it is believed that the occurrence of thyroid cancer is related to hormones. The sex hormones in women's bodies will change during pregnancy and menopause. These hormones may stimulate thyroid nodules, which will trigger the occurrence of cancer cells and lead to thyroid cancer.

5. Thyroid disease

People who have had thyroid diseases before have a very high chance of developing thyroid cancer. For example, if the patient has had goiter, thyroiditis, thyroid hyperplasia and other diseases before, they may all contribute to the occurrence of thyroid cancer. Therefore, if you have a thyroid disease, you must diagnose and treat it in a timely manner.

6. Dietary factors

Of course, thyroid cancer is also related to diet. If you have an irregular diet or often eat foods that are prone to cancer, such as fried or grilled foods, these foods may also cause thyroid cancer.
