BRAIN TUMOR

ABSTRACT -

Multiplication and growth of unstoppable abnormal cells which subsequently results into tumor in brain causes Brain Tumor. These are either cancerous - Malignant or noncancerous- Benign or cancer that spreads to brain from other body parts can also cause brain tumor.

Types:

Primary Brain Tumor –Benign or Malignant

  1. Chordomas – Slowly growing tumors that are most common in people with age 50 to 60.
  2. Craniopharyngiomas – Removing them is a bit complicated because they are located near critical structure of brain.
  3. Gangliocytomas – Rare tumors that include differentiated neoplastic nerve cells.
  4. Glomus jugulare – These are located near the base of the skull.
  5. Meningiomas – Originating from meninges membrane which covers brain and spinal cord.
  6. Pineocytomas- It arises from Penial cells which predominantly occurs in adults.
  7. Pituitary adenomas- Most common intracranial tumors after gliomas, meningiomas and schwannomas.
  8. Schwannomas- They initiate from nerve cells that provides electrical insulation.

Malignant Tumor

  1. Gliomas – Most common adult brain tumor which accounts for 78% of the malignant tumors.
  2. Astrocytomas – Starts from star shaped glial cells, part of supportive tissues in the brain called astrocytes.
  3. Ependymomas – Comprises of 2 to 3 percent of the brain tumor.
  4. Glioblastoma multiforme (GBM) – Grow rapidly and spread to other tissues with poor prognosis.
  5. Medulloblastomas – Most common in children which arises from cerebellum.
  6. Oligodendrogliomas – Derived from myelin making cells.

CAUSES –

The causes are unclear but there are chances of the following causes which might give rise to brain tumor:

  • Inherited gene changes increase the risk of brain and spinal cord tumors
  • Cell alteration which makes the cells multiply uncontrollably can form tumor
  • Certain radiations
  • Contact with harmful chemicals

RISK FACTORS –

  • Stress
  • Family History
  • Exposure to radiation
  • Pre-existing chronic diseases like obesity

SIGNS AND SYMPTOMS –

  • Headache
  • Seizures
  • Difficulty in communication
  • Paralysis on one side of the body
  • Dizziness
  • Vision and hearing changes
  • Tingling
  • Nausea
  • Confusion

DIAGNOSIS –

  • CT scan
  • Magnetic Resonance Imaging (MRI)
  • Magnetic Resonance Spectroscopy – Used to determine the chemical content of the tumor and the nature of lesions.
  • Positron emission tomography (PET scan) – Diagnose recurring tumor cells
  • Biopsy

TREATMENT –

  • Surgery
  • Radiotherapy
  • Chemotherapy

EPIDEMIOLOGY-

  • The incidence of primary malignant tumor is 3.4 % per 100,000 population.
  • Prevalence is 3.9% in males and 3.0% in females per 100,000 population.
