Can thyroid cancer metastasize to the brain? 10

Thyroid cancer can cause brain metastases. Thyroid cancer is a malignant tumor that occurs in thyroid epithelial cells, which is prone to regional lymph node metastasis, bone metastasis and metastasis of other organs through blood circulation. In addition, cancer cells will enter the skull through the carotid artery, and new metastases will appear in the brain, resulting in brain metastases.

Thyroid cancer has a relatively small chance of brain metastases, but as long as brain metastases occur, the symptoms are more severe, causing headaches, nausea, and impaired consciousness. Therefore, if there is brain metastasis in thyroid cancer, it must be checked in time to control the development of the disease and improve the quality of life of patients.

After the occurrence of thyroid cancer in patients, especially in the early stage, the symptoms are relatively hidden, so many patients have reached the middle and advanced stages when they are found, and the phenomenon of spread and metastasis is easy to occur at this time, the most common is brain metastasis or bone metastasis, once metastasis occurs, it is very difficult, but patients should not give up. Common ** regimens for brain metastases of thyroid cancer include the following 4 types.

Clause. 1. Endocrine**. Endocrine** is mainly to choose thyroxine tablets, this drug can prevent hypothyroidism and prevent further aggravation of the condition, and patients should go to the hospital regularly for re-examination during the period of taking the drug.

Clause. 2. Radioactivity**. Radioactivity** is generally the choice of radionuclides** and irradiation**, and the specific use of which one needs to follow the doctor's advice.

Clause. 3. Chemotherapy. Chemotherapy is one of the most common methods for brain metastasis of thyroid cancer, which mainly uses chemical drugs to inhibit the spread of cancer cells to control the disease and improve the survival rate.

Thyroid cancer can metastasize throughout the body, including brain metastases. The most common metastases of thyroid cancer are lung, liver, bone metastases or brain metastases.

Thyroid cancer is the lightest cancer, it will not metastasize, the ** rate is very high, after surgery, take medicine on time for reexamination, there is basically no problem, and normal people, there are no sequelae!

First of all, don't give up**, you should seek medical attention as soon as possible, communicate with the doctor, listen to the advice and actively carry out**.

At present, the most effective methods are: surgery, radiotherapy, chemotherapy and targeted drugs.

Surgery**: Thorough surgery** is one of the effective methods, but surgery ** has certain contraindications, generally for patients with extensive lymph node metastases, but the cancer is still confined to the lymph node capsule, and the mobility is still good, surgery can be used to completely remove it; Surgery for anaplastic carcinoma** should be performed for patients with lymphatic metastases**, which can improve the survival rate of anaplastic thyroid carcinoma.

Radiotherapy: This is one of the local methods of lymphatic metastasis of thyroid cancer, and patients who undergo thyroidectomy will generally destroy the remaining cancer cells with radioactive iodine**. The effect of radiotherapy is affected by the biological effects of radiotherapy, and it is not recommended to give radiation alone to patients with lymphatic metastases of thyroid cancer**, which can be used for palliative treatment of advanced thyroid cancer**.

However, radiotherapy often kills a large number of normal cells while killing cancer cells, which is not conducive to the recovery and consolidation of thyroid cancer after surgery**.

Chemotherapy: Differentiated thyroid cancer responds poorly to chemotherapy and is only selectively used in combination with other methods in some patients with advanced locally unresectable or distant metastases.

Targeted drugs**: Targeted drugs refer to drugs or their preparations that have been endowed with targeted capabilities, and have relatively high ingredients. Specific lesion sites (e.g., vascular growth factor of tumors) can be targeted for accumulation or release.

Toxicity and damage to normal tissues and cells will also be low. Compared with other**, oral targeted drugs have the least physical harm to patients and can improve the quality of life of patients. However, if the patient has developed resistance to radioactive iodine**, a multi-targeted TKI-targeted drug (tyrosine kinase inhibitor)** can be used.

For example, lenvatinib, but this drug is currently only available in Macau and Hong Kong in China, and can be prescribed in hospitals or clinics.

This is determined by many factors, not a simple generalization, the disease site is also different, the final result is also different, although many thyroid cancer has metastasized in the advanced stage, but it means that the patient can still survive for ten years or even more than ten years. How long thyroid cancer can live is also related to many factors, such as age, gender, pathological type, extent of lesions, metastasis or surgical method, among which pathological type is the most important. Patients should go to the local regular hospital as soon as possible to avoid aggravation of the condition.

In most cases, the prognosis for thyroid cancer is better. In general, it can achieve the purpose of clinical **, if it is detected early, especially through physical examination and screening by B-ultrasound, thyroidectomy is performed after discovery, and even some radiotherapy is performed. Now it can basically achieve clinical **, but the overall life expectancy of thyroid cancer is also related to the type of thyroid cancer, most patients with differentiated cancer can also survive for a long time, and the life span of undifferentiated cancer will be relatively affected, and patience is also possible.
