Brain cancer of the head is a whole group of various intracranial neoplasms of a malignant nature, which arose as a result of the launch 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 thorough examination should be done. 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 the location of the lesion.
Cancer Risk Factors
The main "provocateurs" of cancer are:
- work in hazardous industries;
- heredity;
- exposure to radiation;
- smoking;
- HIV infection;
- head injuries.
Signs of Brain Cancer
The clinical manifestations of a brain tumor are affected by its location, as well as the degree of compression and destruction of tissues. As the disease progresses, cerebral symptoms appear , which is caused by intracranial hypertension and impaired hemodynamics. The focal symptom of brain cancer is completely dependent on the location of the tumor.
Focal symptoms of brain oncology
- Decreased sensitivity, in which a person loses the ability to perceive tactile, pain and thermal external stimuli.
- Decreased muscle activity, the occurrence of paresis.
- Epileptic seizures that occur as a result of the formation of a stagnant focus of excitation in the cerebral cortex.
- Hearing impairment and loss of speech recognition ability.
- A symptom of brain cancer, such as auditory and visual disorders, occurs when a tumor is located near the optic nerve.
- Violation of speech and writing.
- Vegetative disorders, which are manifested in weakness, fatigue, fluctuations in blood pressure and pulse.
- Hormonal disruptions.
- Lack of coordination is observed with damage to the midbrain or cerebellum.
- Psychomotor disorders.
- Meaningless hallucinations.
Cerebral symptoms
Intense and prolonged headache is the first symptom of brain cancer and a distinctive feature of all oncological diseases. As a rule, pain in this case is difficult to stop, relief is brought only by lowering intracranial pressure. 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, an increase in the size of which leads to a deterioration in blood supply.
If you have at least one symptom of brain cancer, contact a hospital immediately. Diagnosis of cancer, as a rule, is carried out using histological examination. Only after a complex neurosurgical operation to collect the necessary material can brain cancer be diagnosed, the treatment of which does not always lead to the desired results.
