Are thyroid nodules related to thyroid cancer?

Thyroid nodules are classified as benign and malignant, among which malignant thyroid nodules are thyroid cancer. Thyroid cancer is the most common malignant tumor of the thyroid gland, according to China's Guidelines for the Diagnosis and Treatment of Thyroid Nodules and Differentiated Thyroid Cancer, 5% and 15% of thyroid nodules are malignant (i.e., thyroid cancer), which shows that most of the thyroid nodules are benign and have little impact on the body.

However, in malignancy, some nodules are malignant as soon as they are detected, while others are benign at first and turn malignant later. In other words, benign thyroid nodules should not be taken lightly, and there is a possibility that they may develop into cancer.

According to different clinical stages, the effect of thyroid cancer is also very different. The 5-year survival rate for stage, stage, stage, and stage thyroid cancer is about .., respectively50% and, the later the stage, the lower the survival rate.

Therefore, for benign patients, in order to avoid cancer, it is important to re-examine and actively prevent and control in a timely manner, and it is generally recommended to re-examine every 6 to 12 months.

Benign signs of thyroid nodules mainly include:

The nodule morphology is regular, there is a complete envelope, the nodule can be isoechoic, hyperechoic, mixed echoic and hypoechoic, the ratio of the longitudinal and horizontal diameter of the nodule is less than 1, and the complete sound halo is seen around the nodule, and the color blood flow signal of the ring is measured around the nodule.

The main signs of malignancy of thyroid nodules are:

The nodules are irregular in morphology, there is no obvious capsule or the capsule is incomplete, the nodules are mostly hypoechoic, and even some nodules are echoically attenuated behind them, the ratio of the longitudinal and horizontal diameters of the nodules is greater than or equal to 1, small calcifications are seen in the nodules, and the blood flow signal distribution is disordered, and most of them penetrate from the periphery of the nodules to the inside.

Thyroid nodules can be benign or malignant. Benign mainly includes nodular goiter, thyroid adenoma, etc.; Malignant thyroid nodules are predominantly thyroid cancer. Thyroid nodules should be found as soon as possible, and should not be delayed for too long, otherwise it is easy to cause lesions.

Is there a relationship between thyroid nodule size and thyroid cancer?

Thyroid nodules are a fairly common disease, there are more than 200 million thyroid nodules in China, most of the thyroid nodules are benign nodules, basically do not show any symptoms, generally do not need special treatment, but there are also some patients with thyroid nodules will have the following two typical symptoms.

Some patients with thyroid nodules experience neck pain, as well as a sensation of a foreign body and pressure in the throat, and there are two main reasons for the pain. The first is inflammation, such as laryngitis and tonsillitis, which can cause pain, especially when eating, drinking, and swallowing. The pain will be more pronounced; The second is when the thyroid nodule bleeds due to emotional agitation or a sudden increase in blood pressure, which can also cause pain.

Enlargement is also a typical symptom of thyroid nodules, it occurs for many reasons, the most common of which is a lack of iodine, once the lack of iodine in the body, it will lead to a decrease in the synthesis of thyroxine, and the thyroid-stimulating hormone will be secreted excessively, causing the thyroid gland to enlarge. In addition, thyroid patients can be affected by bacteria or viruses, or if they are under excessive mental stress for a long time, which can lead to thyroid enlargement.

These two are typical symptoms of thyroid nodules, and they can cause other symptoms such as difficulty breathing and swallowing due to enlarged nodules, as well as pain that can cause people to sweat.

Most thyroid nodules do not become cancerous, and only a very small percentage of thyroid nodules become cancerous, and these thyroid nodules that can become cancerous are usually malignant nodules, which are hard, less mobile, and grow faster.

All in all, thyroid nodules, although common, can also be harmful, so once a thyroid nodule is detected, it is important to have further tests and further evaluation, but abnormalities should be done as soon as possible**.

There will be swelling, commonly known as big neck disease, and some people will feel pain around the nodules, hoarseness, etc. Some people's nodules may become cancerous after decades of development.

The most noticeable symptom is the enlargement of the local lump. Thyroid nodules are more obviously characterized by goiter, at this time, the patient's thyroid part of the lump is obvious, these lumps will also move up and down with the person's swallowing action, generally this situation exists, indicating that the thyroid gland has a disease, which is a common sign of local cancer. You should go to the hospital in time to cooperate with the doctor for examination**.

Some thyroid nodules will become cancerous thyroid cancer, but most thyroid nodules are benign, so it is enough to pay attention to them mainly once a year.
