Tumours are abnormal tissues which cells grow & multiply uncontrollably, causing dysfunction of the organ from which it arises.
Brain tumour either originate from the brain itself (Primary) or a cancer at distant site can reach to brain (metastatic).
Primary Brain tumours mainly of two types:
Common Gliomas are
A grade IV astrocytoma is usually called glioblastoma multiforme.
More than 500 new cases are diagnosed with primary brain tumour everyday worldwide and even more are diagnosed with metastatic brain tumour. Incidence & prevalence of brain tumour is growing in India.
Symptoms of Brain tumours vary depending on the part of the brain they affect. Some common symptoms are headaches, seizures, problem with vision, vomiting, difficulty in walking and mental changes, difficulty in speaking and sensation.
It is estimated that nearly 12,800 deaths will be associated with malignant tumours of the brain and other parts of the central nervous system. Fortunately, new and sophisticated techniques have led to advances in the treatment of brain tumours. Tumours that were once inoperable in the brain can now be accessed and removed, sometimes completely, and often without impaired neurological function.
Sophisticated imaging techniques can pinpoint the tumour and determine whether it's growing or shrinking. Diagnostic scanning include CT scan and MRI, which are also used during surgery to guide tissue biopsies and tumour removal. Magnetic resonance spectroscopy (MRS) is used to examine the tumor's chemical profile and see whether the tumour is responding to treatment. PET scan can help detect recurring brain tumours.
Surgery is the main form of treatment for brain tumours. The goal is to remove the entire tumour, whenever possible, without damaging critical neurological functions. Tumour may recur if any tumour cells are left behind. Radiation therapy and chemotherapy are generally used as secondary treatment for tumours that cannot be cured through surgery alone.
