How is a brain tumor recognized?
There are no symptoms that are unique to brain tumors. When symptoms do occur, they are due to damage to the region of the brain where the tumor happens to be located. Thus, tumors in the front of the brain can produce personality changes while tumors in the middle of the brain can affect strength, sensation, and vision. Seizures can also occur with brain tumors, as can headaches. However, a variety of other neurological diseases can cause each of these symptoms. Recognizing that neurological symptoms are due to a brain tumor requires several tests (see below).
