Brain cancer stage 4: symptoms, treatment and prognosis
The term “brain cancer: to perform the 4 stages in medicine understand the whole heterogeneous group of neoplastic diseases of the brain tissue, the membranes of the brain, blood and lymphatic vessels within the cranium, cranial nerves, endocrine glands secretions of the brain (pituitary and hypothalamus) and the skull, which are in final stages of development.

But in this case, the criterion of malignancy is not cellular irregularities (although it is), and the complications that causes such education and a high risk of death.

Can be used the following methods of treatment, both alone and in combination:
- neurosurgical operation – rarely used due to neoperabelnoy tumors (stage 4);
- radiation therapy – relieves patients, because we will apply at the last stage of the cancer process, permitting the human condition;
- chemotherapy is often used in patients with stage 4 as palliative treatment along with radiotherapy.
In some cases people with stage 4 cancer of the brain used experimental methods of treatment, which sometimes give a chance for the prolongation of life.
