BRAIN TUMOR CAUSES |
||
|
The cause of primary brain tumors is
unknown, but people who work with rubber and certain chemicals have
a greater-than-average risk of developing them. There is no evidence
that head injury causes brain tumors, but researchers are trying to
determine the relationship, if any, between brain tumors and
viruses, family history, and long-term exposure to electromagnetic
fields. Symptoms do not usually appear until the tumor grows large enough to displace, damage, or destroy delicate brain tissue. When that happens, the patient may experience: Headaches that become increasingly painful and are most painful when lying down Nausea and vomiting or sudden attacks of vomiting not accompanied by nausea Seizures Dizziness, loss of coordination or balance Personality changes Sudden loss of vision Memory loss Speech problems Sensory changes Mental impairment Weakness or paralysis on one side of the body. A doctor should be notified whenever a patient experiences one or more of the symptoms. |
