A brain tumor is an abnormal cluster of tissue in the brain wherein the cells grow and multiply seemingly out of control. It can be cancerous (malignant) or noncancerous (benign).
A tumor that originates from the tissues of the brain or its immediate surroundings is called a primary brain tumor. Primary brain tumors can be either glial (composed of glial cells) or non-glial (developed in the structures of the brain).
If the cancerous tumor starts from another part of the body, such as the lungs or breast, and spreads into the brain, it is called a secondary brain tumor or metastatic brain tumor.
Because having a brain tumor can be a very serious condition, it is good to be aware of the symptoms it causes. There are several signs that may manifest, but it is not likely that a person suffering from a brain tumor would have them all. Symptoms may also differ depending on the size and the location of the tumor in the brain.
