What are the hazards of glioma

Gliomas are a common disease in the brain. They are highly malignant and can endanger the patient's life at any time. They are a severe test for the patient's physical and mental abilities. The harm of gliomas is also immeasurable. Let's take a look at the harms of gliomas.

Gliomas are more common in men, especially glioblastoma multiforme and medulloblastoma, which are significantly more common in men than in women. All types of glioblastoma are more common in middle-aged people, ependymoma is more common in children and young people, and medulloblastoma almost always occurs in children. The location of glioma is also related to age. For example, cerebral astrocytoma and glioblastoma are more common in adults, while cerebellar glioma (astrocytoma, medulloblastoma, ependymoma) is more common in children.

Glioma usually has no typical symptoms at the beginning. As the tumor grows, it will show the following symptoms: one is increased intracranial pressure and other general symptoms, such as headache, vomiting, vision loss, diplopia, epileptic seizures and mental symptoms. The other is local symptoms caused by the compression, infiltration and destruction of brain tissue by the tumor. The local symptoms vary depending on the location of the tumor.

Glioma is an infiltrative growth with no clear boundary between it and normal brain tissue. It is difficult to completely remove it, is not very sensitive to radiotherapy or chemotherapy, and is very prone to recurrence. Benign and malignant tumors growing in important parts of the brain are difficult to remove surgically or cannot be removed at all. Chemical drugs and general anti-tumor Chinese medicines are not ideal in efficacy due to the influence of factors such as the blood-brain barrier. Therefore, brain glioma is still one of the tumors with the worst prognosis among all tumors in the body.

Some tumor patients have epilepsy symptoms, which may be early symptoms. Epilepsy that begins in adulthood is generally symptomatic and is mostly caused by brain tumors. Those who are difficult to control with drugs or whose seizures change in nature should be considered to have brain tumors. Those with tumors adjacent to the cortex are more likely to develop epilepsy, while those with tumors deep inside are less likely to develop epilepsy. Localized epilepsy has localization significance.
