Brain Tumor

A brain tumor is an abnormal growth of cells in the brain or nearby structures. Brain tumors can be benign (noncancerous) or malignant (cancerous). Even a benign tumor can cause problems if it puts pressure on important areas of the brain.

What causes a brain tumor?

In most cases, the exact cause of a brain tumor is unknown. Certain factors may increase the risk of specific types of brain tumors, including:

• Exposure to high doses of ionizing radiation.
  
• Family history or certain inherited genetic syndromes.
  
• Certain medical conditions.

Brain tumors can also develop when cancer from another part of the body spreads to the brain. Some cancers that can spread to the brain include lung, breast and kidney cancers, as well as melanoma.

Symptoms of a brain tumor

Symptoms depend on the tumor's type, size and location. Some symptoms develop gradually, while others may appear or worsen more quickly.

Symptoms may include:

• Persistent or unusual headaches.
  
• Nausea or vomiting.
  
• Seizures.Changes in vision or hearing.
  
• Balance problems or difficulty walking.
  
• Weakness or numbness in part of the body.
  
• Difficulty speaking or understanding.
  
• Memory or concentration problems.
  
• Changes in behavior or personality.

Having these symptoms does not necessarily mean you have a brain tumor, as they can also occur with other conditions.

How is a brain tumor diagnosed?

Evaluation may begin with a medical history and a neurological examination, which can assess strength, coordination, balance, vision and hearing.

Depending on the case, testing may include:

• Magnetic resonance imaging (MRI).
  
• Computed tomography (CT) scan.
  
• Biopsy to analyze a tissue sample.
  
• Molecular testing to identify specific characteristics of the tumor.

These tests help determine the type and characteristics of the tumor and guide treatment planning.

Treatment for brain tumors

Treatment depends on the tumor's type, size, location, grade and characteristics, as well as the patient's overall health.

Treatment options may include:

• Surgery.
  
• Radiation therapy or radiosurgery.
  
• Chemotherapy.
  
• Targeted therapy.
  
• Monitoring with regular imaging for some small, symptom-free tumors.

Different treatments may be combined depending on the individual case.

Living with a brain tumor

Regular medical follow-up is important to monitor the condition and manage symptoms. Some patients may benefit from physical, occupational or speech therapy, as well as emotional support.

Care and follow-up should be tailored to each patient's needs.

When should you see a specialist?

See a Neurology or Neurosurgery specialist if you experience new, persistent or worsening symptoms, especially seizures, neurological changes, vision problems, difficulty speaking or weakness.

A first-time seizure, sudden weakness or numbness, sudden difficulty speaking, sudden vision loss or a sudden severe headache requires immediate medical attention.

3. What are the symptoms of a brain tumor?

Symptoms may include persistent headaches, seizures, vision or hearing changes, balance problems, weakness, and changes in speech, memory or behavior.

4. How is a brain tumor diagnosed?

Evaluation may include a neurological examination and imaging tests such as an MRI or CT scan. A biopsy may be needed in some cases.

5. Does every brain tumor require treatment?

Not necessarily. Some small tumors that do not cause symptoms may be monitored with regular imaging, while others require treatment based on their characteristics.
