Malignant brain tumors occur in about 4.5 people per 100,000 inhabitants, which can occur at any age but brain cancer is the leading cause of cancer death in patients under age 35. In adults, the incidence is generally highest between the ages of 40 to 60.
There are two main types of cancer brain. Primary brain cancer starts in the brain. Metastatic brain cancer starts somewhere else in the body and moves to the brain. The most common tumor types in adults are gliomas and meningiomas. In children, the incidence is generally highest before age 1 and again between the ages of 2 and 12. The most types most common brain tumors in children are astrocytomas, medulloblastomas, ependymomas and brain stem gliomas.

Causes of Brain Cancer
What causes brain cancer is not known exactly, but recently there has been a lot of speculation about the role of cell phone radiation the development of brain cancer. In fact, while studies generally have shown no link between cell phones and brain cancer, there is some conflicting scientific evidence that may be worth further study, according to the FDA.

More risk factors for brain cancer include, exposure to vinyl chloride and people with risk factors such as having a job at an oil refinery, as a chemist, embalmer, or employee of the rubber industry show higher rates of brain cancer. Other risk factors like smoking, exposure to radiation, and viral infection (HIV) have suggested, but has not been shown to cause brain cancer. Patients with a history of melanoma, lung, breast, colon or kidney cancer are at risk of cancer Secondary brain.

SIGNS AND SYMPTOMS OF BRAIN CANCER
Onset of symptoms is usually insidious and brain tumors are often misdiagnosed. Brain cancer causes changes in the central nervous system, invading and destroying tissues and by secondary effects, such as pressure on the brain. Symptoms vary, but in general, brain cancer symptoms include: abnormal pulse and breathing, deep, headaches that recur often and persist without relief opaque for long periods of time, difficulty walking or speaking, dizziness, vision problems, double vision, convulsions, vomiting and in the latter stages of the disease dramatic changes in blood pressure can occur. Although headaches are often a symptom of brain cancer, is important to remember that most the headaches are due to less serious conditions such as migraine or tension, not cancer.

Diagnosis of brain cancer
In the most cases a definitive diagnosis is made using a tissue biopsy. Other diagnostic tools include: patient history, neurological evaluation, X-ray skull, a brain scan, CT scan, MRI, lumbar puncture and cerebral angiography. Meningiomas arising from coverage of the entire brain or spinal cord, representing about 20% of brain cancers and are generally more benign.

TREATMENT OF BRAIN TUMORS
How to treat brain tumors depends on patient age, stage of disease, type and location of the tumor, and whether the cancer is a primary tumor or metastases brain. Brain cancer and brain tumors are somewhat unique because of the blood
blood-brain barrier, which severely restricts the type of substance in the bloodstream that are required by the body in the brain and makes drug treatment extremely difficult. Because of this increasingly research is being done drug delivery through nanoparticles, between the properties of nanoparticles that make them ideal candidates to recognize and treat brain cancer, its ability to offer a wide variety of payloads through the blood-brain barrier is perhaps the most important.

Brain cancers of the location and ability to spread quickly makes treatment with surgery or radiation like fighting an enemy hiding among minefields and caves, and explains why term brain cancer is too often associated with the word inoperable.
Survival statistics for the deadliest brain cancer tumors as gliomas have not improved significantly over the past two decades and the clinical instrument is to a large extent, still dependent on surgery and radiotherapy, treatments known to leave survivors with devastating cognitive deficits. Surgery Gamma Knife radiosurgery is a technique used to treat people with brain tumors and other neurological disorders

The deadliest form of brain cancer may be treatable with a vaccine that uses proteins. Unlike measles or mumps, which are intended to prevent the disease, the vaccine against brain cancer activates the patient's own immune system by This will help to remove the tumor. When injected vaccine, which stimulates the immune system to kill cancer cells in the brain and prevent the regrowth of tumors and have been treated.

PROGNOSIS
The chances of surviving a person with a brain tumor: Prognosis depends largely on all the features following: type of extension of tumor size and location of disease presence or absence of tumor metastases in tumor response to therapy, age, overall health and medical history, tolerance for specific medications or therapies. Metastatic brain cancer indicates advanced disease and has a poor prognosis. Unfortunately, the most common form of primary brain cancer, glioblastoma, is also the most aggressive and deadly, but teratomas and other germ cell tumors, although they have the capacity to grow very large may have a more favorable prognosis.
