However, it is clear that brain tumors are not contagious. No one can "catch" the disease from another person. Research has shown that people with certain risk factors are more likely than others to develop a brain tumor. A risk factor is anything that increases a person's chance of developing a disease.Most brain tumors in children originate when a normal cell begins to grow abnormally and reproduce too rapidly. Eventually these cells develop into a mass called a tumor. The exact cause...

brain

What is the brain?he brain is a soft, spongy mass of tissue. It is protected by the bones of the skull and three thin membranes called meninges. Watery fluid called cerebrospinal fluid cushions the brain. This fluid flows through spaces between the meninges and through spaces within the brain called ventricles. A network of nerves carries messages back and forth between the brain and the rest of the body. Some nerves go directly from the brain to the eyes, ears, and other parts of the head. Other nerves run through the spinal cord to connect the brain with the other parts of the body. Within the brain and spinal cord, glial cells surround nerve...
