Description of Brain Cancer
Brain cancer is the abnormal growth of cells in the brain. Though growths on the brain are often referred to as tumors, not all tumors are cancerous. Only malignant, or spreading cells, are called brain cancer. When a tumor does not spread it is a benign tumor. Brain cancer is the leading cancer in patients under the age of 35. There is no specific cause for brain cancer.

Types
-
Primary tumors originate in the brain as cells change and grow abnormally. The cells may multiply and form clumps. Metastatic tumors form in other areas of the body. The abnormal cells spread and transfer the cancer to the brain.
Symptoms
-
Symptoms for brain cancer vary from the size of the tumor as well as the location. Sharp pains and headaches that increase in severity can occur. A person with brain cancer can have blurred vision and dizziness. Severe mood changes can take place. Other symptoms include seizures and hearing problems.

Cause
-
The cause of brain cancer is not known. It can be hereditary, and radiation to the head as well as smoking have all been linked to cancer. Patients with a history of other diseases such as breast and lung cancer can be diagnosed with brain cancer as the primary cancer begins to spread.
Diagnosis
-
A CT-Scan can see images in three dimensions including brain tumors. Once a medical review has been completed, a scan is usually preformed. An MRI is also preformed if a brain tumor is found. An MRI can see more specific changes in tumor growth and development. Other tests such as blood work, liver function and urinalysis may be performed. If a tumor is viewed on the CT-Scan or MRI, a biopsy is taken; the entire skull does not need to be opened for a biopsy. A small hole is drilled into the skull and a needle is inserted. A pathologist will examine the sample under a microscope.
Treatment
-
The treatment will vary among patient and depends on the age, physical history, location and size of tumor. Tumors may be surgically removed. Radiation kills cancerous cells and stops them from growing by using a high-energy rays. Chemotherapy also kills cells by using a combination of pharmaceutical treatments. More than one method of treatment is commonly used.
