Function

• There are a variety of symptoms and sign of brain tumors. These symptoms depend on where in the brain the tumor is located, how big it has grown and how fast it is growing. Different parts of the brain have control over different functions. A tumor growing in a certain part of the brain can cause problems for those bodily functions that that area has power over.
  
  

Effects

• Some of the symptoms of brain tumors are headaches that over time become more frequent and more severe. Vomiting and bouts of unexplained nausea are signs of a tumor of the brain, as are blurred or double vision. The loss of your peripheral vision can indicate a brain tumor. Losing your balance and having trouble with your speech are symptoms, as are becoming confused easily. A radical change in personality or behavior is a sign. So, too, are hearing problems and seizures for someone that has not had a previous history of them.
  
  

Significance

• Of all the symptoms of a brain tumor, the headache is the most common, with almost half of all tumor patients complaining of headaches. Everyone suffers from a headache at some point in their life, but if you begin to experience headaches unlike any you have ever had, along with nausea and throwing up, there could be a brain tumor behind them. Nearly a third of brain tumor patients have seizures before their tumor is diagnosed.
  
  

Considerations

• The symptoms of nausea and vomiting alone don't point to a brain tumor as the cause, but when they accompany other symptoms, they can. Vision problems are one symptom that can be easily noticed and brought to the attention of a physician. If you have constant double vision or cannot see off to the sides as you look ahead, these are serious signs that could signify a tumor as the culprit.
  
  

Warning

• Onset of weakness in the extremities can denote a tumor. The arms, legs and even the muscles of the face can become weak due to a tumor's effects. Odd feelings inside your head and a strange feeling in your hands that you will be hard pressed to describe can imply a tumor. These symptoms are also similar to those of a stroke, and should be reported immediately. If you have a hard time recognizing familiar objects or people, or cannot find the right word repeatedly, a tumor could be the reason. A total loss of previous inhibitions can mean you have a brain tumor as well.
