Symptoms of brain metastasis from thyroid cancer

What are the symptoms of thyroid cancer brain metastasis?

1. Thyroid cancer patients will have brain metastasis, and they will experience headaches, nausea, vomiting and blurred vision. Multiple intracranial metastatic lesions can also cause cerebral edema, which can be manifested in severe cases as obvious projectile vomiting or even coma, leading to internal environmental disorders and abnormal urination.

2. In severe cases, brain metastases can compress brain tissue, causing edema and increased intracranial pressure, leading to nausea, vomiting and other discomfort symptoms. Patients with deep metastases in the cerebral cortex will have symptoms of cognitive dysfunction.

How to diagnose early symptoms of brain cancer?

Brain cancer includes primary brain cancer such as glioma and secondary brain cancer such as secondary brain metastases such as lung cancer, breast cancer, thyroid cancer, colorectal cancer, leukemia, lymphoma, etc. The early symptoms of these tumors mainly refer to the tumors being located in important functional areas or close to the cerebral cortex. Therefore, symptoms appear before the tumor is large in size and has not yet caused obvious mass effect and increased intracranial pressure. The main manifestations are weakness or hemiplegia of one limb, complete or incomplete aphasia, decreased vision, hemianopsia, focal or generalized epilepsy.

The most important examination method for diagnosing brain tumors is magnetic resonance imaging, which can determine whether there is a mass in the brain and the general condition of the mass. However, imaging examinations, including magnetic resonance imaging, cannot determine the specific pathological nature of the tumor and can only be determined through puncture biopsy. Clinically, the diagnosis of brain cancer requires a multi-faceted basis to fully diagnose brain cancer, which is very important for brain cancer patients.
