Prevention Of Brain Cancer
In general, there is no known way to prevent brain cancer. However, early diagnosis and treatment of tumors tend to metastasize to the brain can reduce the risk of metastatic brain tumors. Avoid or reduce exposure to radiation (especially the head) and avoid toxic chemicals associated with oil and rubber, chemicals for embalming and other environmental toxins can help prevent brain cancer. Preventing HIV infection is also suggested.
Treatment Of Brain Cancer
Treatment of a brain tumor depends on many factors. These include the location, type and size of the tumor, as well as the patient's age and general health. Treatment methods and schedules often vary for children and adults. Management plan has been developed to meet the needs of each patient.
The patient's physician may want to discuss this issue with other medical treatment of brain tumors. In addition, patients may want to talk to a doctor involved in the search for new cures. Such studies are called clinical trials.
Many patients want to learn all they can for their disease and treatment options, so that they can actively participate in decision-making for their medical care. A brain tumor a person has a lot of questions, and the doctor is the best person to answer. Most patients want to know what kind of cancer they have, how it can be treated, how effective the treatment is likely to be, and what is likely to cost.
Many people find it useful to list of questions before seeing the doctor. Taking notes can make it easier to remember what the doctor said. Some patients have also found it helps to have a family member or friend when talking to the doctor or taking part in the discussion or just listen.
Patients and their families have much to learn about brain tumors and their treatment. They should not feel they need to understand everything the first time they see fit. They will have other opportunities to ask the doctor to explain things that are not clear.
What test is used to detect and diagnose adult brain tumors?
Tests that examine the brain and spinal cord are used to detect (find) adult brain tumor. The following tests and procedures may be used:
Computed tomography (CT): A procedure that makes a series of detailed pictures of areas inside the body taken from different angles. The photos are taken by a computer linked to an x-ray machine A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography.
MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves and a computer to make a series of detailed pictures of the brain and spinal cord. A substance called gadolinium is injected into the patient through a vein. Gadolinium collects around the cancer cells so that they appear brighter in the picture. This procedure is also called nuclear magnetic resonance imaging (NMRI).
Adult brain tumor is diagnosed and removed during surgery. If a brain tumor is suspected, a biopsy is done by removing part of the skull and using a needle to remove a sample of brain tissue. A pathologist examines the tissue under a microscope for cancer cells. If cancer cells are detected, the doctor will remove as much tumor as safely possible during the same surgery. An MRI can be performed to determine whether cancer cells remain after surgery. Also perform tests to determine the extent of tumor.

Symptoms Of Brain Cancer
Brain cancer may not cause symptoms in its earliest stages when it is best treated. When symptoms occur, they can vary among individuals and vary depending on the stage of advancement, and where the cancer is localized in the brain.
Many symptoms of brain cancer is caused by the impact of the growing tumor on the brain and spinal cord. Symptoms are usually neurological in nature and include:
Balance problems, difficulty walking, and falls
Blurred or double vision
Changes in hearing, taste or smell
Mood, personality or behavior
Difficulties with memory, thinking, speaking, understanding, writing or reading
Dizziness or lightheadedness
Headache, which may be worse in the morning, or lying
Incoordination
Muscle twitching, convulsions or seizures;
Muscle weakness
Nausea and vomiting
Numbness or tingling in the arms or legs

Causes Of Brain Cancer
As with tumors in other parts of the body, the exact cause of most brain tumors is unknown.
The following factors have been proposed as possible risk factors for primary brain tumors, but whether these factors actually increases the risk of a person with a brain tumor is not known with certainty.
Radiation to the head
An inherited (genetic) risk
HIV infection
Smoking
Environmental toxins (eg, chemicals used in oil refineries, embalming chemicals, chemicals in the rubber industry)

Brain Cancer Overview
Brain cancers are the result of abnormal growth of cells in the brain. Brain cancer can arise from primary brain cells, cells that form the other components of the brain (eg, membranes, blood vessels), or the growth of cancer cells that develop in the other organs have spread to the brain via the blood (metastatic brain cancer).
Although many brain tumors are popularly known as brain tumors, brain tumors are not all are cancerous. Cancer is a term reserved for malignant tumors.
Malignant tumors grow and spread aggressively, overpowering healthy cells by taking their space, blood and nutrients. Like all body cells, cancer cells need blood and nutrients to survive. This is particularly a problem in the brain due to increased growth to the limits of the skull can lead to increased intracranial pressure or distortion of vital surrounding structures, causing them to malfunction.
The tumors that grow aggressively are called benign. Almost all cancers that start with the brain do not spread to other parts of the body. The main difference between benign and malignant tumors is that malignant tumors can invade the brain tissue and grow rapidly. This rapid growth of the borders of the skull can rapidly cause damage to surrounding brain tissue.
In general, benign tumors is less serious than a malignant tumor. However, even benign tumors can cause many problems in the brain, but usually the problems progressed more slowly than malignant tumors.
Sometimes people confuse cerebral aneurysms with brain tumors. Cerebral aneurysms are tumors are the areas of arteries or veins of the brain are abnormally low and extend to form a ball or the expansion of the vessel wall. Rarely causes symptoms unless they begin to leak blood into the surrounding brain tissue. Aneurysms can be congenital (from birth) or extended or formed in the vessels of the brain after an injury to the vessel (eg, trauma, atherosclerosis, hypertension), but are not formed from cancer cells. Unfortunately, when the aneurysm produces symptoms that may resemble those produced by brain tumors.
Primary brain tumors
The brain consists of different types of cells and tumors that arise from cells of the brain of a type known as primary brain tumors.
Cancers occur when one type of cell changes and loses its normal characteristics. Once transformed, the cells grow and multiply abnormally.
As these abnormal cells grow, they become a mass of cells or a tumor.
Brain tumors caused by this transformation and abnormal growth of brain cells called primary brain tumors because they originate in the brain.
The tumors are the most common primary brain gliomas, meningiomas, pituitary adenomas, vestibular schwannomas, CNS lymphomas and primitive neuroendocrine tumors (medulloblastoma). Glioma is a broad term that includes many subtypes, including astrocytomas, oligodendrogliomas, ependymomas, choroid plexus papillomas and.
These primary tumors are named for the type of brain cells or brain from which they arise.
The brain tumors vary in their growth and ability to cause symptoms. The cells are rapidly growing, aggressive tumors usually show an abnormal microscopic. The National Cancer Institute (NCI) uses the classification system for classifying tumors. NCI lists the following degrees:
Grade I: The tissue is benign. The cells seem almost like normal brain cells, and cell growth is slow.
Grade II: The tissue is malignant. The cells look less like normal cells with cells from a tumor grade I.
Grade III: The malignant tissue has cells that look very different from normal cells. The abnormal cells are growing. These anomalies occur in cells called anaplastic.
Grade IV malignant tissue has cells that resemble the most unusual and tend to grow very quickly.
United States, are primary brain tumors and other cancers of the nervous system are estimated to develop in about 22,000 people in 2010, according to the National Cancer Institute.
Metastatic brain tumors
Metastatic brain tumors are made of cancer cells that spread through blood from a tumor located elsewhere in the body. The most common cancers that spread in the brain are those caused by cancer that starts in the lung, breast and kidney cancer and malignant melanoma, a skin cancer. The cells spread to the brain from another tumor in a process called metastasis. The process of metastasis occurs when cancer cells leave the primary cancer tissue and enter the lymphatic system is to reach the blood or the blood directly. These cancer cells eventually reach the brain tissue through the bloodstream, where they develop into tumors.
Metastatic brain tumors are the most common type of tumor in the brain and are much more common than primary brain tumors. Metastatic tumors are usually named after the type of tissue from which cancer cells home took place (for example, lung metastases or metastatic breast cancer). Brain blood flow usually determines how metastatic cancer cells will lodge in the brain, approximately 85% located in the brain (the largest part of the brain, located at the top of the cavity of the skull.) Unfortunately, most Metastatic brain tumors occur in more than one place in the brain tissue.
