Among the deadly ailments people suffer from, Brain tumor deserves special mention. The tumor stems from the brain cells in a human body in case of a Primary brain tumor. On the other hand, secondary or derived brain tumors occur in the instances when the cancerous cells from lung, breasts or other body parts reach the brain. The majority of the brain tumor cases are caused by the latter where the cancerous cells use the blood streams to spread to brain.

Brain tumorcan be divided into certain categories. One variant is meningioma which stems from the cover of the human brain. This can be removed and cured by surgery. There is another variant called astrocytoma that can prove to be deadly. The classification system, introduced by WHO in 1993, is generally practiced in diagnosing brain tumor types. The incidence of children being infected with brain tumor is on the rise in the USA .

Brain Tumor Symptoms

As a matter of fact, people suffering from Brain tumor can develop a number of symptoms and it is subject to the brain part that is infected. There are however some common symptoms. As the tumor grows in dimension, it creates pressure on the skull which in medical terms is known as raised intracranial pressure. The affected person feels chronic headache and nausea.

What Causes Brain Tumor

Unfortunately the causes behind the occurrence of Brain Tumor still remain unclear. One usual suspect is the excess ionizing radiation given to head. Certain genetic reasons can also play a role. A theory also points at the increased use of electronic devices like cell phones that radiate electromagnetic waves.
