Brain tumor - a formation in the brain state of abnormal cells. There are many different brain tumor. Some of these are non-cancerous (benign), some - cancerous or cancerous. Tumors that begin to grow in the brain, called primary; tumors that spread to the brain from other parts of the body are called secondary or metastatic. The choice of treatment of brain tumors is dependent on its species, size and location.

Symptoms

The symptoms of brain tumors depend on its rate of growth, size, and from where it is located. Among the common and the most common symptoms of the tumor:

• The emergence of headaches Headache: Causes and Complications   or change in the nature of headaches

Causes

• Primary brain tumors

Primary brain tumors begin to develop in the brain or surrounding tissues such as the meninges and cranial nerves. Swelling begins to grow when normal cells there is a mutation of DNA. These mutations allow cells to grow and multiply abnormally fast, and live longer than they can live healthy cells. The result of this process is the mass of abnormal cells that forms a tumor.

Primary brain tumors are much rarer secondary. These tumors are called depending upon the type of cells involved in their formation:

• Acoustic neuroma (schwannoma)
• Astrocytoma, also known as gliomas, which includes anaplastic astrocytoma and glioblastoma
• Ependymoma
• Ependymoblastoma
• Germ cell tumors
• Medulloblastoma
• Meningoblastoma
• Sympathicoblastoma

• Secondary brain tumor

Secondary or metastatic brain tumors start to grow in other parts of the body and extend at a certain stage in the brain. Such tumors can be caused by many types of cancer, including such as:

• Breast Cancer
• Colon cancer
• Kidney cancer
• Lung cancer
• Melanoma

Risk factors

So far it is not known exactly what causes the DNA mutations in the cells, but it is assumed that brain cancer may be the following risk factors:

• Race. Brain tumors are the most common among Caucasians. The exception is meningioma - it often occurs in blacks.
• Age. The risk of cancer of the brain increases with age. However, there are many exceptions. For example, certain types of brain cancer, such as medulloblastoma occur almost exclusively in children.
• Exposure to radiation Radiation and its biological effect: gently infected! . People exposed to ionizing radiation, are at risk of cancer of the brain and some other types of cancer. Examples of ionizing radiation is radiation therapy Radiotherapy in cancer treatment: irradiation aid   (which is used to treat cancer), radiation which is formed by the explosion of the atomic bomb. More common examples of radiation, such as radiation from mobile phones or microwave ovens, according to some experts, also increase the risk of cancer, but so far no one is able to prove.
• Exposure to chemicals, particularly what is happening on a regular basis (for example, if it is associated with the work of man) also increases the risk of developing brain tumors.
• Brain tumors in the family history. The likelihood of developing brain cancer Brain cancer - is it possible to cure?   those whose close relatives have suffered from this disease, slightly higher than the rest.

Very often, the early stages of cancer has no symptoms and those symptoms that appear are nonspecific and can easily be mistaken for symptoms of other disorders. People with an increased risk of cancer (for example, smokers who abuse alcohol, those who are regularly exposed to sunlight, and those who have a genetic predisposition to cancer) is especially important to know the symptoms and to follow closely the changes in his condition.
