Symptoms of Brain Tumors

Symptoms depend largely on the tumor's location, size, and how fast it is growing. Symptoms may suddenly appear or get progressively worse over time. Symptoms include:

Headache

Headache is a very common symptom of a brain tumor, though very few headaches are from a tumor. The headache happens because of increased pressure in the skull caused by growth of the tumor itself, swelling from tissue around the tumor, or a blockage of fluid that surrounds the brain and spine.

Headaches due to tumors tend to worsen over time and are not relieved with standard approaches. They are often most painful when waking up in the morning and may be associated with visual changes, like double vision.

Seizure

For some people, having a seizure is the first sign of a brain tumor. A seizure can occur suddenly and sometimes without warning. However, there are people who feel a change or signal (called an aura) before the seizure occurs.

A seizure may be:

  • Generalized or major motor —May cause violent shaking, which may include losing consciousness. There may be loss of urine or bowel control, or biting of the tongue. These seizures begin in one part of the brain, but spread throughout the brain.
  • Focal —These may cause one part of the body to shake uncontrollably. It may start in one area and progress to a generalized seizure. A focal seizures may also occur without any shaking. They may or may not involve a change in consciousness.

Not all seizures include shaking of body. Some seizures are quick changes of consciousness, which may cause a person to fade out for a brief period.

Other General Symptoms    TOP

Increased intracranial pressure may cause other symptoms, such as:

  • Nausea and/or vomiting
  • Blurred, double, or loss of vision
  • Increased fatigue and/or sleepiness
  • Difficulty maintaining balance

Other Physical and Neurological Symptoms    TOP

If the tumor is pressing on or growing into nearby brain tissue, certain functions may be affected. Symptoms are dependent on tumor location, but changes may be noticed with:
