Primary Brain Tumors
Brain tumours – a heterogeneous group of various intracranial neoplasms, benign or malignant, arising from the start of the process of abnormal uncontrolled cell division, which in the past were normal components of the brain tissue itself, lymphatic tissue, blood vessels of the brain, cranial nerves, meninges, skull, glandular formations brain. The type of tumour is determined by the cells that form it.
Tumours that develop from brain tissue are the primary formations of the brain. Primary tumours develop from mutated cells that make up the central nervous system (neurons (rarely), glial cells, vascular endothelial cells, cells that form the membrane of the brain or nerve membrane, etc.), or their precursors (stem cells).
Types of primary tumours
The following types of brain tumors are distinguished:
- glioma;
- astrocytoma;
- ependymoma;
- oligodendroglioma;
- medulloblastoma;
- meningioma;
- schwannoma;
- craniopharyngea.
Of the malignant tumours, glioblastoma (a tumour from neuroglia, a complex of auxiliary cells of the nervous system that surround neurons and perform important functions in the development and maintenance of the structure of the central nervous system) and metastatic tumours are most common.
Symptoms
If you notice the appearance of the following symptoms, you should consult a doctor:
- Headache, which often occurs in the morning.
- Vomiting.
- Loss of balance, slowness and clumsiness.
- Drowsiness.
- Violation of visual function expressed in double vision and fog before the eyes.
- Inhibition and confusion.
- Fatigue.
- Cramps.
Surgery
Surgical treatment of brain tumours is the main, most effective method, however, removing the tumour from the brain tissue is a significant challenge. Each such intervention is a complex neurosurgical operation. Since the surgeon needs to excise the tumour within healthy tissues, each such operation is traumatic, and often completely impossible due to the large size of the tumour.
Depending on the size, location, type of tumour, the patient’s condition, a decision is made about the need for surgery, the amount of surgery and how it is performed. The use of modern laser and ultrasound equipment in the surgery of brain tumours has made it possible to slightly increase its effectiveness. The specific route of intervention and the method of its implementation is individual and depends on the location of the tumour, its size and cellular composition.
