- In children: Juvenile pilocytic astrocytoma, craniopharyngioma, medulloblastoma, brain stem glioma and germ cell tumours.
- In adults: Astrocytoma, oligodendroglioma, ependymoma, meningioma, vestibular Schwarzkopf and lymphoma. Cancers from other parts of the body can also spread to brain.
- Headaches, usually in the morning
- Vomiting
- Convulsions or seizures
- Weakness in limbs
- Loss of balance while walking
- Altered speech or vision
- Altered behavior
- Loss of orientation
- Memory lapses
- Imaging: CT scan or MRI scan of brain is commonly performed.
- Biopsy: A piece of tumor is removed for examination by open surgery or in stereo tactic fashion using rigid frame to fix skull and localizing tumor under guidance of CT scan or MRI.

- Surgery: Maximum safe resection of the tumor or at least a biopsy is the standard goal of surgery.
- Radiation therapy: Radiation kills tumor cells with high energy X-rays, gamma rays or protons. It is usually started after surgery and given over 5-6 weeks.
- Chemotherapy: Chemotherapy is the use of drugs to kill cancer cells. It is given orally or through veins. It is given concomitantly with radiation therapy in high-grade tumors. It is also given in recurrent brain tumours after failure of initial treatment.
- 3-Dimensional Con formal Radiation Therapy (3D-CRT) and Intensity Modulated Radiation Therapy (IMRT)
- CT scan and MRI are used to delineate the tumor and computers are used for radiation planning. Only the tumor and the high-risk region surrounding the tumor is radiated, avoiding radiation to the normal structures in the brain.
- Stereo tactic Radio-surgery (SRS) and Stereotactic Radiotherapy (SRT): Highly precise immobilization and image guidance system is used for treatment of selected brain tumors. High dose of radiation is delivered only to the tumour with very minimal spillage of dose to the rest of the sensitive brain structures. Stereo tactic radiotherapy is preferred in children. Stereotactic radio-surgery delivering high-dose of radiation in single or a very few sessions is performed in adults with tumors such as metastatic residual glioma, meningioma and schwannoma. Novalis-Tx and Cyberknife are advanced machines to deliver such high-precision therapy.
- High-definition Rapid Arc: This is the latest software advancement in radiation planning technology. Radiation is delivered in continuous fashion moving the machine head and its small components simultaneously around the patient’s head targeting the tumour by infinite small radiation beams. Radiation treatment with such a technique is highly precise and fast. This is preferred in children and elderly patients who cannot lie on treatment couches for long periods.
- Proton beam therapy: Proton therapy avoids spillage of radiation dose to the surrounding brain. It is preferred in children as well as in patients with recurrent tumors who have received radiation therapy earlier.
