Not all brain tumors cause symptoms, and some (such as tumors of the pituitary gland) are often not found unless a CT scan or MRI is done for another reason. The symptoms of brain cancer are numerous and not specific to brain tumors, meaning they can be caused by many other illnesses. The only way to know for sure what is causing the symptoms is to undergo diagnostic testing. Symptoms can be caused by:
A tumor pressing on or encroaching on other parts of the brain and keeping them from functioning normally.
Swelling in the brain caused by the tumor or surrounding inflammation.
The symptoms of primary and metastatic brain cancers are similar.
Astrocytoma is a type of brain cancer that usually starts in the cerebrum, the largest part of your brain, but can also show up in the cerebellum (the back of the brain). It’s more common in men than women and most often shows up after age 45. There are several types of astrocytoma, and some grow faster than others.
They get their name from astrocytes, the star-shaped cells where they form in the brain. About 50% of primary brain tumors are astrocytomas.

Gradual changes in intellectual capacity or emotional response
In many people, the onset of these symptoms is very gradual and may be missed by both the person with the brain tumor and the family. Occasionally, however, these symptoms appear more rapidly. In some instances, the person acts as if he or she is having a stroke.
When to Seek Medical Care
Seek emergency medical help right away if you have any of the following symptoms:
Although headaches are thought to be a common symptom of brain cancer, they may not occur until late in the progression of the disease. If any significant change in your headache pattern occurs, your health care provider may suggest that you go the hospital.
If you have a known brain tumor, any new symptoms or relatively sudden or rapid worsening of symptoms warrants a trip to the nearest hospital emergency department. Be on the lookout for the following new symptoms:
Changes in mental status, such as excessive sleepiness, memory problems, or inability to concentrate
Visual changes or other sensory problems
Difficulty with speech or in expressing yourself
Changes in behavior or personality
Clumsiness or difficulty walking
Nausea or vomiting (especially in middle-aged or older people)
