malignant brain, spinal cord and other nervous system tumors in 2003. Approximately

13,100 people in the United States will die from brain, spinal cord, and other nervous

system tumors in 2003. Brain and spinal cord tumors occur most often in children younger

than 10 years of age, whereas in adults, these tumors are most common in the third to fifth

decades of life. Brain tumors form because, the body normally forms new cells only when

they are needed to replace old or damaged ones. If something happens to disturb this

controlled process, abnormal or excessive cells are produced. When this occurs a tumor is

developed. This is known as cancer. When a tumor is developed on the brain, it is called a

brain tumor or brain cancer. Brain tumors can be benign or malignant (benign being not

cancerous and malignant being cancerous). Both types can be deadly when dealing with the

brain. Benign brain tumors consist of very slow growing cells. They have di

spread to other parts of the body. Brain tumors can initially start in the brain. They can

tumors when located on the brain they can cause death. Because of their location brain,

brain cancer. Brain tumors are the second leading cause of death in the age group 15-34.
