Brain Tumors
What is a brain tumor?
A brain tumor is a mass of abnormal cells in the brain. There are many types of brain tumors. They may start in the brain (primary tumors) or travel to the brain from another part of the body (metastatic tumors). Brain tumors may be slow growing, not likely to spread, and not cancer (benign). Or they may be quick growing, able to spread to other parts of the brain, and cancer (malignant). Both kinds of brain tumors can cause serious problems by pressing on and damaging normal brain tissue. Symptoms will depend on the type of tumor, how big it is, and where it is in the brain.
What causes symptoms?
Brain tumors can cause many different symptoms. Things such as where the tumor is and how fast it grows (aggressiveness) are important. A tumor can cause symptoms in a variety of ways. These include:
-
Destroy normal brain
-
Compress normal brain
-
Cause swelling of the brain
-
Increase pressure in the head (intracranial pressure)
-
Cause seizures (convulsions or epilepsy)
-
Cause bleeding in the brain
-
Cause hydrocephalus by blocking the normal flow of cerebrospinal fluid. CSF is a clear fluid that bathes, supports, and cushions the brain and spinal cord.
What are the symptoms?
The most common symptoms of brain tumors are:
-
Headaches that may be worse in the morning or with activity
