Brain Tumour

A brain tumor, or tumour, is an intracranial solid neoplasm, a tumor (defined as an abnormal growth of cells) within the brain or the central spinal canal.Brain tumors include all tumors inside the cranium or in the central spinal canal. They are created by an abnormal and uncontrolled cell division, usually in the brain itself, but also in lymphatic tissue, in blood vessels, in the cranial nerves, in the brain envelopes (meninges), skull, pituitary gland, or pineal gland. Within the brain itself, the involved cells may be neurons or glial cells (which include astrocytes, oligodendrocytes, and ependymal cells). Brain tumors may also spread from cancers primarily located in other organs (metastatic tumors). The most common primary brain tumors are:[3]Gliomas (50.3%); Meningiomas (20.9%);Pituitary adenomas (15%);Nerve sheath tumors (8%).

Headache in person under 6 years old brain tumor, hydrocephalus
Person over 50 years old with pain at temples arteriĆÆtis temporalis
Pregnancy with unknown headache pre-eclampsia
Increased headaches after trauma sub/epidural hematoma
Severe headaches and very high blood pressure malignant hypertension
Acute severe headache meningitis, CVA (Cerebrovascular accident or stroke), subarachnoidal hemorrhage
Headache and fever (with reduced consciousness) meningitis
Stiffness of the neck/neurological dysfunction meningitis, brain tumor
Headache with signs of elevated intracranial pressure brain tumor
Focal neurological dysfunction brain tumor
Early morning vomiting or vomiting unrelated to headache or other illness brain tumor
Behavioral changes or rapid decline in school results brain tumor

Neurosurgeons take the time to observe the evolution of the neoplasm before proposing a management plan to the patient and his/her relatives. These various types of treatment are available depending on neoplasm type and location and may be combined to give the best chances of survival:

  • surgery: complete or partial resection of the tumor with the objective of removing as many tumor cells as possible (Video)
  • radiotherapy (radiosurgery)
  • chemotherapy, with the aim of killing as many as possible of cancerous cells left behind after surgery and of putting remaining tumor cells into a nondividing, sleeping state for as long as possible

Intracerebral brain tumour.

Survival rates in primary brain tumors depend on the type of tumor, age, functional status of the patient, the extent of surgical tumor removal and other factors specific to each case.
