Put in layman's terms, that is 1 in every 161 men and women throughout the world will in some way be affected by the disease.
When trying to determine whether someone has brain cancer or not, it helps to have a basic understanding of what exactly the brain is, and what role the brain plays in the body.
The brain is the control center of the nervous system (the computer), which is made up of soft tissue (60% fat), and where the cerebral (the main part of the brain) has between 15 - 35 million neurons ([nerve cells] a core component of the nervous system) that are each connected to synapses (structures) that permit electrical or chemical signals to be passed to other cells.
The brain controls what someone does or does not do, by using a highly complex message system that passes messages backwards and forwards via a network of nerves. These may be things that someone is conscious of, such as walking and talking, or things that the body
