If a tumor grows on the thalamus, it develops very quickly. Generally, the thalamus does not grow tumors, and if a tumor grows, 80-90% of the possibilities are malignant, with gliomas predominating. Neuroglioma is the most common form of intracranial malignant tumor, the growth mode is the same as the growth mode of weeds, infiltrative growth, it can erode the surrounding neural tissues and other tissues in all directions, thus resulting in the trend of malignant growth, the growth is very fast, sometimes even 1 or 2 months will produce very obvious clinical symptoms. If it is indeed a glioma, the grade is even higher and the degree of malignancy is even greater, and some patients can even only survive for 3-6 months. If a tumor grows on the thalamus, it must be treated promptly with appropriate treatment modalities, including surgery, radiotherapy and chemotherapy.
