Cancer of the brain of the head is a whole group of various intracranial neoplasms of a malignant nature, which arose as a result of the start of the process of uncontrolled division of abnormal cells. Despite the fact that such a pathology is very rare, its consequences in most cases are very deplorable, therefore, at the first alarming symptoms of the disease, a deep examination should be carried out. As a rule, the type of tumor is determined by the cells from which it is formed, and the first symptoms of brain cancer depend on the histological variant and localization of the lesion.
Risk factors for cancer
The main "provokers" of cancer are:
- work in hazardous industries;
- heredity;
- exposure to radiation;
- smoking;
- HIV infection;
- injuriesheads.
Signs of brain cancer
The clinical manifestations of a brain tumor are affected by its location, as well as the degree of compression and tissue destruction. As the disease progresses, cerebral symptoms appear, which are caused by intracranial hypertension and hemodynamic disturbances. The focal symptom of brain cancer depends entirely on the location of the tumor.
Focal symptoms of brain cancer
-
The first symptoms of brain cancer Decrease in sensitivity, in which a person loses the ability to perceive tactile, pain and thermal external stimuli.
- Decrease in muscle activity, occurrence of paresis.
- Epileptic seizures that occur as a result of the formation of a congestive focus of excitation in the cerebral cortex.
- Hearing loss and loss of speech recognition.
- Such a symptom of brain cancer as auditory and visual disorders occurs when the tumor is localized near the optic nerve.
- Impaired speech and writing.
- Autonomic disorders that manifest as weakness, fatigue, fluctuations in blood pressure and pulse.
- Hormonal failures.
- Disturbance of coordination is observed with damage to the midbrain or cerebellum.
- Psychomotor disorders.
- Senseless hallucinations.
Cerebral symptoms
Intense and prolonged headache is the first symptom of cancerof the brain and a distinctive feature of all oncological diseases. As a rule, pain in this case is difficult to relieve, only a decrease in intracranial pressure brings relief. In addition, a person may experience vomiting and nausea, especially during meals, as well as severe dizziness, which occurs due to compression of the cerebellar structures. This condition can also be triggered by the growth of a tumor, the increase in the size of which leads to a deterioration in blood supply.
If you have even one symptom of brain cancer, go to the hospital immediately. Diagnosis of oncological diseases, as a rule, is carried out with the help of histological examination. Only after a complex neurosurgical operation to take the necessary material can one diagnose brain cancer, the treatment of which does not always lead to the desired results.
