How and why developing brain cancer
Brain cancer can be primary (arising in the brain tissue) and secondary, which has spread to the brain tissue by metastasis of some other body.
Primary brain cancer often occurs when the brain tissue has already some pathological process. This may be, for example, post-injury or inflammation, benign tumor
A benign tumor - is not always safe
. There are a number of environmental factors that contribute to the formation of cancer. This genetic predisposition, constant intoxication carcinogens in the workplace and at home (especially dangerous in this regard, oil products and chemicals produced during the manufacture of rubber), ionizing radiation (radiation), smoking.
Under the influence of environmental factors in the brain tissue in a particular area begin to multiply uncontrollably tissue cells. At the same time they lose their common characteristics, that is, become abnormal. Emerging tumor can compress the surrounding tissue, causing a disruption of the bodies for which the tissues responsible. In addition, under the influence of the tumor may occur swelling of brain tissue. The more different tumor cells from the tissue cells, from which they originated, the more malignant the tumor is considered.
Signs
Symptoms of brain cancer can be divided into local (focal) and cerebral. Alopecia called signs, that arose as a result of irritation or destruction of brain tissue to grow replacement or her tumor. On these grounds (primary local symptoms, you can determine exactly where the tumor is located, since certain parts of the brain responsible for well-defined function of the body. There may be a violation of gait, movements, sensitivity, vision. There is also a secondary local symptoms, which are caused by trauma to the surrounding tumor tissues. There are no clear boundaries between these symptoms are not present.
Cerebral symptoms often presented headache. When brain tumors headache almost always occurs and is often the first sign of the disease. Headache is usually bursting with character prevails in the morning, after a dream

When tilting the head voltage. This headache is a consequence of increased intracranial pressure. Pain may be preceded by a feeling of heaviness in the head, general discomfort, malaise. In the development of the disease becomes a constant headache. Often the headache is accompanied by nausea and vomiting.
More than half of patients develop psychiatric disorders. They develop in the later stages of the disease. The development of mental disorders depends on the age of the patient: they develop in children is extremely rare in the elderly - often. These disorders are cerebral response to cancer. Reduced attention, concentration, perception and comprehension difficult is happening around, all mental processes are slowed. Patients speak slowly, struggling for words, broken memorization, orientation in the environment. Patients are being rapidly depleted, fail to respond to their surroundings and fall in the drowsy state.
All these changes often grow quite slowly and elderly people can be mistaken for normal age-related changes. Brain cancer distant metastasis seldom gives
Metastasis - danger everywhere
Usually it is spread on the brain tissue.
Diagnostics
The preliminary diagnosis the doctor may have to put on the basis of the interview and examination of the patient. In addition, conducted electrophysiological (elektoentsefalografiya), X-ray (including computed tomography and magnetic resonance imaging), radiology, laboratory (study of cerebrospinal fluid) diagnostics.
In some cases, further diagnosis biopsy of brain tumor. This operation, which is performed under general anesthesia and involves taking a piece of tumor tissue for analysis and possible removal of the tumor (if possible).
Conservative therapy of brain cancer is auxiliary. Enter the means of reducing intracranial pressure, severe headaches - pain relievers, if convulsions - anticonvulsants. According to the testimony prescribe bracing, hypnotics, cardiovascular, anti-anxiety agents.
Radical method of treatment is surgical removal of the tumor. Radiation therapy is often used after surgery and less as an independent method of treatment. In some cases, radiation therapy combined with chemotherapy
Chemotherapy - it always falls the hair?
- The introduction of drugs that suppress tumor growth.
Brain cancer - a serious disease, but timely treatment for medical assistance it is quite possible to overcome.
