How is brain cancer diagnosed?


A number of tests will be performed to investigate symptoms of brain cancer and confirm a diagnosis. Some of the more common tests include:[1]

  • a physical examination
  • imaging tests such as a computerised tomography (CT) scan or magnetic resonance imaging (MRI)
  • taking a sample of tissue (biopsy) from the brain for examination under a microscope.
  • molecular testing of biopsy sample to guide treatment options
  • lumbar puncture to look for cancer cells in the cerebrospinal fluid (CSF), the liquid that surrounds the brain and spinal cord.
