Brain and spinal cord tumors are masses of abnormal cells in the brain or spinal cord that have grown out of control.
The brain is the center of thought, feeling, memory, speech, vision, hearing, movement, and much more.Tumors or other problems in this part of the brain typically cause weakness, but in rare cases can cause tremor or other involuntary movements.Cerebellum: The cerebellum lies under the cerebrum at the back part of the brain. Tumors of the cerebellum can cause problems with coordination in walking, trouble with precise movements of hands, arms, feet, and legs, problems swallowing or synchronizing eye movements, and changes in speech rhythm.Brain stem: The brain stem is the lower part of the brain that connects to the spinal cord.
It contains bundles of very long nerve fibers that carry signals controlling muscles and sensation or feeling between the cerebrum and the rest the body.For this reason, doctors usually speak of “brain tumors” rather than “brain cancers.” The main concerns with brain and spinal cord tumors are how readily they spread through the rest of the brain or spinal cord and whether they can be removed and not come back.
