Brain cancer of the head is a whole group of different intracranial tumors malignant nature that have arisen as a result of the launch of the process of uncontrolled division of abnormal cells.Despite the fact that this pathology is very rare, the consequences of it in most cases, very grim, so at the first warning signs of disease should undergo a profound examination.Typically, the tumor type is determined by the cell from which it is formed, and the first symptoms of cancer of the brain depend on the embodiment and the histological localization of the lesion.
Risk factors for cancer
main "instigators" of cancer are:
- work in hazardous industries;
- heredity;
- exposure to radiation;
- smoking;
- HIV infection;
- head injury.
Symptoms of brain cancer
on clinical manifestations of brain tumors affect its location, and the degree of compression and tissue destruction.As the disease progresses, cerebral symptoms manifested, which is caused by intracranial hypertension and impaired hemodynamics.Focal same symptom of cancer of the brain is totally dependent on the tumor.
focal symptoms of brain cancer
- desensitization, in which a person loses the ability to perceive tactile, thermal and painful external stimuli.
- Reduced muscle activity, the occurrence of paresis.
- Epileptic seizures, which result in the formation of the cerebral cortex of stagnant excitation center.
- hearing and loss of the ability to recognize speech.
- Such a symptom of brain cancer as auditory and visual disorders, occurs when the location of the tumor 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.
- incoordination observed in lesions of the midbrain or cerebellum.
- Psychomotor disorders.
- Senseless hallucinations.
cerebral symptoms
intensity and duration of a headache - the first symptom of brain cancer and distinguishing feature of all cancers.As a rule, the pain at the same time are difficult to cupping, it brings relief to a reduction in intracranial pressure.In addition, a person may experience vomiting and nausea, especially during the meal, as well as severe dizziness, which occurs due to the compression of the cerebellar structures.This condition can also be triggered by tumor growth, increasing the size of which leads to a deterioration of the blood supply.
If you showed at least one symptom of cancer of the brain, immediately contact the hospital.Diagnosis of cancer, as a rule, is carried out using histological examination.Only after neurosurgical operations difficult fence required material can diagnose cancer of the brain, the treatment of which does not always lead to the desired results.
