Characteristics of glioma after onset

Nowadays, there are a lot of people suffering from glioma, many of which are caused by environmental pollution or excessive stress. Glioma is extremely harmful to people and can even threaten their lives. So, what are the symptoms of glioma? Let's take a look at the symptoms of glioma.

Gliomas are the most common primary brain tumors caused by the canceration of glial cells in the brain and spinal cord. Like other tumors, gliomas are caused by the interaction of congenital genetic high-risk factors and environmental carcinogenic factors. Some known genetic diseases, such as neurofibromatosis and tuberculous sclerosis, are genetic susceptibility factors for gliomas.

The neuroimaging characteristics of glioma are: the course of the disease is diffuse infiltration growth, with a wide range and unclear boundaries, swelling of brain tissue in the affected area, shallow or disappeared grooves, and smaller ventricles. The space-occupying effect is often not obvious in the early stage of the lesion, and the midline structure is often not shifted. The space-occupying effect may be manifested in the middle and late stages of the lesion. If the lesion is biased to one side, signs of space-occupying effect may appear earlier. Tumor cells often invade two or more parts of the cerebral hemispheres, and both the cortex and subcortical white matter may be affected.

1. Glioma cells have the ability to escape immunity, making it difficult for the body to naturally produce specific killer cells and antibodies against them, thus effectively circumventing the inhibition and clearance of the human immune system.

2. The pathophysiological type of each glioma patient is often very different. Glioma of the same type and grade also have obvious differences. Modern neuroscience can predict the growth rate, invasiveness, and sensitivity to radiotherapy and chemotherapy of the tumor by testing the specific protein or gene expression of the tumor through methods such as immunohistochemistry.

3. Most of them grow and recur in situ, while a few metastasize or spread within the skull or central nervous system (brain, spinal cord). There are few cases of metastasis outside the central nervous system.
