Brain Cancer

Brain cancer or tumours is an abnormal growth of cells in the brain. Malignant tumours can grow and spread aggressively to distant parts of the body as well. Tumours that do not spread or invade nearby tissue are called benign. Benign tumours are less harmful as compared to malignant ones, but a benign tumour can cause problems in the brain by pressing on a nearby tissue.

Brain tumours that originate in brain cells are called primary brain tumours. The most common primary brain tumours are gliomas, menin-giomas, pituitary adenomas, vestibular schwannomas, and primitive neuroectodermal tumors (medulloblastomas). The term glioma includes glioblastomas, astrocytomas, oligodendrogliomas, and ependymomas.

Metastatic or secondary brain tumors spread to the brain from other tumors. Symptoms of a brain tumor are usually related to its location rather than its size. Symptoms develop when the tumor destroys or compresses normal brain tissue. Either the tissues around the tumor swell or the tumor interferes with the normal flow of fluid around the brain and spinal cord.

Symptoms to Look For:

  • Headache
  • Seizures
  • Speech problems
  • Imbalance or difficulty in walking
  • Impaired vision or a restricted visual field

Having any of these symptoms does not mean it is cancer, but if one or more of them is noticed for more than two weeks, then a doctor must be seen and an immediate health screening is a must.

Diagnosis of Brain cancer can be done by Physical examination, MRI or CT scan, Biopsy through surgery or Stereotactic brain biopsy. Treatment of brain cancer is usually complex. The most widely used treatments are surgery, radiation therapy, and chemotherapy. Many people with brain tumours undergo surgery or a stereotactic brain surgery in which the tumour is removed with the assistance of image guidance, leaving the healthy brain relatively intact. Neuro-endoscopy is another minimally-invasive surgical procedure where the tumour is removed through small holes in the skull, mouth or nose, enabling neurosurgeons to access areas of the brain that cannot be reached with traditional surgery.

Radiation therapy and chemotherapy are other modalities of treatment. A state-of-the-art centre for treatment of brain tumours has specialized neuro-oncologists, neurosurgeons and advanced radiation technology for coordinated treatment and support focused on helping the patient to conquer the disease and to maintain quality of life.
