How harmful is glioma to humans?

Glioma is a common intracranial malignant tumor in young and middle-aged men. Relevant epidemiology shows that the incidence of glioma has been increasing year by year in recent years. Glioma will seriously endanger people's health. Therefore, relevant oncology experts say that glioma should be discovered and treated early. If glioma is not treated actively, serious complications will occur. So, how harmful is glioma to people?

1. Mental Disorders

It is caused by progressive increase in intracranial pressure, or it can be the result of compression and destruction of the brain substance by tumors. The early symptoms are generally mild, manifested as apathy, dullness, memory and comprehension impairment, etc. As intracranial pressure continues to increase, mental symptoms become more obvious, such as dementia, confusion, personality and behavior changes, etc.

2. Triggering epilepsy

The incidence rate accounts for about 30% of brain tumors. It is mostly caused by direct stimulation or compression of the tumor. The seizure type is often localized, but it can also be a major seizure. The seizure is related to the location and nature of the tumor. For example, tumors in the motor area and its vicinity have a higher incidence of epilepsy. Glioma, astrocytoma and oligodendroglioma have a higher incidence rate.

3. Tumor Bleeding

Patients with a small amount of bleeding may have no symptoms or very mild symptoms. Patients with a large amount of bleeding may show symptoms of high intracranial pressure, hemiplegia, aphasia, and in severe cases, loss of consciousness, brain herniation, or even sudden death.

4. Limb Paralysis

Most cases are hemiplegia. The incidence is higher in patients with tumors located near the motor area of ​​the brain, the basal ganglia, or the ventral side of the brainstem. It starts as mild paralysis, which gradually develops into severe paralysis and even complete paralysis. Hemiplegia is accompanied by other manifestations, such as symptoms of high intracranial pressure.

5. Causes Blindness

There are not many people who go blind suddenly due to brain tumors. Often, vision loss occurs first. If it is not treated promptly and effectively, it will gradually develop into blindness. Some children, and even a few adult patients, ignore the loss of vision on one side, and the doctor finds that one eye is blind during the examination. Some patients, especially the elderly, have eye diseases accompanied by brain tumors. When vision changes, they mistakenly think it is an eye disease, delay treatment, and develop blindness. Common tumors include craniopharyngioma, pituitary adenoma, glioma, glioma and high intracranial pressure caused by brain tumors.
