The most common type of brain tumor is a glioma.
Brain tumors that occur in infants and children are very different from adult brain tumors. They may grow back after treatment.īrain tumors can occur at any age. Malignant brain tumors can spread to other parts of the brain or to the spinal cord, but don’t usually spread to other areas of the body. Malignant brain tumors usually grow fast, and grow into nearby tissue. This kind of tumor does contain cancer cells. These tumors can cause symptoms depending on their size and location in the brain. Most benign brain tumors don’t grow into nearby tissue. In most cases, once a benign tumor is removed, it doesn’t grow back. This kind of tumor doesn’t contain cancer cells. These parts include the muscles in the face and around the eyes.īrain tumors start in the cells of the brain. The cranial nerves carry messages between different parts of the upper body to the brain. Many of the cranial nerves start in the brain stem. Part of the brainstem helps control breathing and the heart beat. It plays a part in controlling muscles and sensations from the body. It is the part of the brain that connects to the spinal cord. It includes the midbrain, the pons, and the medulla. It organizes muscle movement and helps to maintain posture, balance, and equilibrium. This includes seeing, hearing, smelling, touching, and feeling pain.
It also helps with understanding information from the senses. It controls thoughts, emotions, and speech, and movement. The cerebrum has two sides, the right and left hemispheres. The brain is part of the central nervous system (CNS). A brain tumor is an abnormal growth of tissue in the brain.
