Brain Cancer

Brain cancer is caused by tumors developing in the brain or, more commonly, by tumors from other parts of the body that spread to the brain. Tumors, or growths, result from an abnormal production of extra cells, which form a mass of tissue. When tumors appear in the brain and spinal column, or central nervous system (CNS), they are especially problematic because one's thought processes and movements may be affected. Such tumors can also be difficult to treat because the tissues surrounding them may be vital to functioning. Brain Cancer presents a clear overview of the causes, symptoms, treatments, and science of this deadly disease.
