Brain Tumor and Brain Injury

A brain tumor is abnormal cells in the tissues of the brain. Primary brain tumors can be either malignant which contain cancer cells or benign which do not contain cancer cells. If a cancerous tumor starts elsewhere in the body, it can spread cancer cells, which grow in the brain.

• Brain tumors can occur at any age
• Researchers and doctors don't grasp actual reason behind brain tumors
• Risk factors embody exposure to radiation and case history of brain tumors

Brain injury refers to the occurrence of an insult to the brain which causes damage. Because every injury damages a special a part of the brain. It can happen at birth or may arise later from trauma or an illness. All traumatic brain injuries are head injuries. But head injury is not necessarily brain injury. There are two types of brain injury traumatic brain injury which is caused by an external force and acquired brain injury which occurs at the cellular level.
