Signs and tests:

A doctor can often identify signs and symptoms that are specific to the location of the tumor. Some tumors may not show symptoms until they are very large and cause a rapid decline in the person's mental functions. Other tumors have symptoms that develop slowly.

Most brain tumors increase pressure within the skull and compress brain tissue because of their size and weight.

The following tests may confirm the presence of a brain tumor and identify its location:

• CT scan of the head
• MRI of the head
• EEG
• Examination of tissue removed from the tumor during surgery or CT-guided biopsy (may confirm the exact type of tumor)
• Examination of the cerebral spinal fluid (CSF) may reveal cancerous cells
