Brain Tumors also vary according to where exactly they are found. The brain is protected by bone structures that closely encase this very important organ. As a result, any tumor in the skull (which protects the brain) can quickly interfere with its functioning. The brain is vital to life, and this can complicate treatments. It is important to thoroughly discuss your options with your physicians. The causes for brain tumors are not well understood. They are not related to known cancer risk factors and early diagnosis is rare.

Anatomy of the Brain The brain and spine make up the main parts of the central nervous system (CNS), and are the control center of the body and mind. The CNS controls everything from movement, sensation, and speech to thought, emotion, and memory. Messages to and from the brain to the rest of the body are transmitted via the spinal cord.
