symptoms of Brain Cancer
One of the main features of brain tumors is that they develop in severely limited space of the cranial cavity, that sooner or later leads to the defeat of both adjacent to the tumor, and distant from it of the brain.

Compression or destruction due to germination of the tumor in prilezhaschiyu to her brain tissue causes the appearance of the primary (so-called focal, local, local, alopecia) symptoms.

As the disease progresses, cerebral symptoms may appear, emerging from the proliferation of cerebral edema, the generalization of hemodynamic and occurrence of intracranial hypertension (increased intracranial pressure), however, with the tumor in the "mute" functionally insignificant, the area of the brain of such a sequence of symptoms can not be and the disease starts with cerebral symptoms, while focal symptoms may be absent altogether.

1. Headache - usually a cerebral symptom, but may be focal in brain tumors associated with richly innervated dura mater.

2. Vomiting - usually a cerebral symptom.

3. Violation of view - is common in pituitary adenomas.

4. Violation of the function of cranial nerves - a violation of smell, blockage of the eyeballs, pain and / or numbness of the face, paresis of facial muscles, hearing loss, impaired balance, swallowing difficulties, taste, etc.

5. Focal symptoms - the severity and nature of the focal symptoms is largely determined by the functional role of the destruction zone (violation of the movements, paralysis, breach of sensitivity, seizures, speech disorder, intellectual and psychiatric disorders, various hallucinations, blurred vision, hyperkinesis, pain, autonomic and hormonal disorders loss of coordination). All patients with newly arisen epileptic seizure shown CT or MRI of the brain to exclude a mass in the brain ..

Despite the small incidence of these tumors, they represent an important chapter of modern oncology: the painful neurological symptoms (paralysis and paresis, Confusion, severe headaches, hallucinations) cause prolonged suffering, and existing medical therapies involve the development of a variety of side effects. Advances in neurosurgery, radiotherapy and chemotherapy to date not very large. Traditionally, the first line therapy of primary brain tumors is surgery and radiation therapy. However, radical surgery is not feasible in all patients, as is often the location of the tumor and its size did not allow for the operation, but radiation and chemotherapy for gliomas are often resistant.

The peculiarity of the flow of malignant glioma is a high propensity to develop recurrence: the 60-90% of patients have local recurrence (often within 2 cm from the primary tumor), 2-year period is experiencing only 15% of patients. Standard approaches to the treatment of relapse does not exist: some of the patients subjected to repeated surgical intervention, most patients preferred chemotherapy, although today it is considered palliative.
