A brain tumor is an abnormal growth of cells within the brain, which can be cancerous (malignant) or non-cancerous (benign).

Brain tumors are classified as:

  • Primary. It refers to brain tumors that originate in the brain and rarely spreads beyond the central nervous system.

  • Secondary (or metastatic). They are brain tumors that originate from cancer cells that have migrated from other parts of the body.

Observed symptoms of brain tumors may depend on tumor size, location and rate of growth. Headaches are a common initial symptom and get worse in the morning, with improvement gradually during the day, but they become more frequent and more severe. Seizures symptoms are caused by a disruption in the normal flow of electricity in the brain. Those sudden bursts of electricity may cause convulsions, unusual sensations, and loss of consciousness. A number of symptoms may be caused by brain tumors or by other problems. Therefore, the only sure way to tell if a patient have a brain tumor is to see a doctor and get neurological exam and tests.

Types of primary brain tumors:

Astrocytoma  Brain metastasis Brainstem glioma CNS lymphoma
Craniopharyngioma  Ependymoma Germinoma  Glioblastoma multiforme
Medulloblastoma Meningioma  Mixed gliomas Oligodendroglioma

Astrocytoma and glioblastoma multiforme (GBM) account for nearly 85% of all brain tumors, with the remainder spread among the other types.

Doctors use many tests to diagnose and identify the type of brain tumor:

- Physical and neurological exam.

- Biopsy.

- Magnetic Resonance Imaging (MRI scan).

- Computed Tomography scan.

- Positron Emission Tomography (PET scan).

- Cerebral angiogram (Arteriogram).

- Myelogram.

- Difussion Tensor Imaging (DTI scan).

- Magnetic Resonance Spectroscopy (MRS scan).
