  • Genetic factors and family history.
  • HIV infections.
  • Exposure to harmful radiations.
  • Unhealthy lifestyle or eating habits, along with the habit of smoking, which multiply the risks.

  • Surgery

    The goal of surgery is to carefully remove the tumour and affected the skin. It aims to restrict the tumour from spreading further. This is the first step for treatment, and the tissue extracted can be tested under the microscope to confirm glioblastoma diagnosis.

  • Radiation Therapy

    After the surgery, radiation therapy is performed. An external beam of radiation is focused or pointed on the affected area to kill the cancerous cells. Proton therapy, interstitial radiation, or brachytherapy are some of the common radiation therapies used for treatment. The procedure reduces the chances of damage to surrounding brain tissues.

  • Chemotherapy

    Chemotherapy uses drugs to deactivate the cancerous cells and stop their growth. The drugs can either be given orally or injected directly. The treatment destroys cancerous cells and prevents their reproduction.
