After getting such information, the doctors first go for neurologic exam.  This check up includes checks for alertness, muscle strength, coordination, reflexes and response to pain. An eye exam is also administered in order to examine the eye swelling that is resulting due to tumor pressing on the nerve that connects the eye and the brain.

There are different test and exams that are requested by the doctors based on the results come after the physical and neurologic examinations

Computerized Tomography (CT):

It is an advanced method that is used in the diagnosis of brain tumor.  In this test a series of detailed pictures of brain are created with link of computer and x-Rays machine. These images let the doctor to spot the tumor existence in the brain. Sometimes , the doctors may injected a special dye into a vein before scan  and due to this dye it become feasible for the doctors to make a difference in the tissues of the brain.

Magnetic Resonance Imaging (MRI):

In this test, a powerful magnet linked to a computer with the mean of which the pictures of brain are created. Sometimes dye may be used for making difference in the tissue of the brain. The color difference of tissue also helps the doctors to detect the tumor of brain.

Angiogram/ Arteriogram:

In this method the doctors takes a series of X-rays after injecting a special dye into an artery. The dye flows through the blood vessels of brain and then doctor see it on the X-rays. With the mean of such procedure the doctors identify the brain tumor.

Brain Scan:

In this test the doctors identify the tumor of brain by observing the areas abnormal growth in the brain that is recorded on a special film. At start the doctors injected a small radioactive material into the vein. This material is not dangerous and leaves the body within 6 hour. This material absorbs in the tumor therefore growth shows up on the film.

Some other test that make it possible for the doctors to identify the cause of brain cancer and also help in diagnosis are Biopsy ,MR spectroscopy, Positron Emission Tomography (PET) , functional imaging , Myelogram etc.

The researchers have come up with some of the risk factors which are more likely to develop and cause brain tumor. The risk factors increase the individual’s chances of developing the diseases.

Some of the high risk factors which are associated to the development of brain tumor are as follows;

Being male: Generally, brain tumors are more and more common in males rather than in females. Though, females have more chances of developing meningiomas.

Age: Mostly, the brain tumor is diagnosed in people who are over the age of 60years or older. Never the less, the brain tumor is the second most common cancer diagnosed in children. Brain tumors are most common in children younger than 8 years of age as compared to older children.

Race: Brain tumors are mostly likely to occur among white people rather than people from some other races.

The Family History: People with such family members who have the problem of glioma’s are more likely to develop this disease.

People who are being exposed to the nuclear and radiation department or certain chemicals at work have more risk and likelihood of developing a brain tumor.

The scientists and researchers are still investigating over that whether the use of cell phones may cause brain tumor or not. Studies done till now do not disclose any validity to this research that people who use cell phones have a high risk of getting brain tumor.

Head injuries are also considered to be a vital component associated with a brain tumor.  Here you can also see what is brain cancer.

Primarily, the tumors in the brain are located in posterior cranial fossa in children and in the anterior two by third of the cerebral hemispheres in the adults, although they can affect any part of the brain.

In US year 2005, as estimated there were 43,800 cases of brain tumor; reported by the central brain tumor registry of US, statistical reports 2005-2006, which accounted for around 1.4percent of all cancers reported, 2.4percent of deaths which were caused by cancer, 20 to 25percent because of pediatric cancer, eventually making it nearly 13,000 deaths each year in the United States only because of brain tumor.

The symptoms and reasons of brain tumor may depend upon two most crucial factors: the tumor volume (size) and the location where tumor has taken place. These are the two factors beginning in the stage of infection correlating with the nature of the brain tumor in some cases. It happens that the tumor grows slowly and show the symptoms late or grows quickly showing early symptoms; one of the frequent reasons to seek medical attention to the brain tumor cases.

Depending upon the tumor size and location along the damage it may cause to the areas surrounding the brain’s structure either because of infiltration or compression or any other kind of neurologic systems may occur which can be tremors, behavioral and cognitive impairment, double vision, changes in the personality, hemi paresis, facial paralysis, hypo esthesia, visual field impairment, ataxia, aphasia etc.

The above mentioned symptoms are not specifically for the brain tumor, but these may be caused because of high neurologic conditions such as traumatic brain injury or stroke. What matters is the location of the functional system and the trauma which it affects.

There are different types of brain tumor, which are; brain metastases, glob blastema multiforme, mixed glioma’s, mixed glioma’s, medulla blastema, expend moa, astrocytoma, craniopharyngioma, CNS lymphoma, brain stem glioma, Shawna noma, germinoma, oligodendroglioma and men angioma
