Brain
Tumour
A cerebrum tumour is a mass or development of strange cells in your mind. A wide range of kinds of cerebrum tumours exist. Some mind tumours are noncancerous (considerate), and some cerebrum tumours are destructive (harmful). Cerebrum tumours can start in your mind (essential cerebrum tumours), or malignancy can start in different parts of your body and spread to your cerebrum (optional, or metastatic, mind tumours).How quickly a brain tumour grows can vary greatly. The growth rate as well as location of a brain tumour determines how it will affect the function of your nervous system.Brain tumour treatment options depend on the type of brain tumour you have, as well as its size and location.
v Types:-
- Acoustic
neuroma
- Astrocytoma
- Brain
metastases
- Choroid
plexus carcinoma
- Craniopharyngioma
- Embryonal
tumours
- Ependymoma
- Glioblastoma
- Glioma
- Medulloblastoma
- Meningioma
- Oligodendroglioma
- Pediatric
brain tumours
- Pineoblastoma
- Pituitary
tumours
vSymptoms:-
The signs and symptoms of a brain tumour vary greatly and depend on the brain tumour’s size, location and rate of growth.
General signs and symptoms caused by brain tumours may include:
- New
onset or change in pattern of headaches
- Headaches
that gradually become more frequent and more severe
- Unexplained
nausea or vomiting
- Vision
problems, such as blurred vision, double vision or loss of peripheral
vision
- Gradual
loss of sensation or movement in an arm or a leg
- Difficulty
with balance
- Speech
difficulties
- Confusion
in everyday matters
- Personality
or behaviour changes
- Seizures,
especially in someone who doesn't have a history of seizures
- Hearing
problems
v Causes
Brain tumours that begin in the
brain
- Primary
cerebrum tumours start in the mind itself or in tissues near it, for example, in
the mind covering films (meninges), cranial nerves, pituitary organ or pineal
organ.
- Primary
brain tumours begin when normal cells acquire errors (mutations) in their DNA.
These mutations allow cells to grow and divide at increased rates and to
continue living when healthy cells would die. The result is a mass of abnormal
cells, which forms a tumour.
- Primary
brain tumours are much less common than are secondary brain tumours, in which
cancer begins elsewhere and spreads to the brain.
v Many different
types of primary brain tumours exist.
Ø Gliomas. These tumours begin in the brain or spinal cord and include astrocytomas, ependymomas, glioblastomas, oligoastrocytomas and oligodendrogliomas.
Ø Meningiomas. A meningioma is a tumour that arises from the membranes that surround your brain and spinal cord (meninges). Most meningiomas are noncancerous.
Ø Acoustic neuromas (schwannomas). These are benign tumours that develop on the nerves that control balance and hearing leading from your inner ear to your brain.
Ø Pituitary adenomas. These are mostly benign tumours that develop in the pituitary gland at the base of the brain. These tumours can affect the pituitary hormones with effects throughout the body.
Ø Medulloblastomas. These are the most common cancerous brain tumours in children. A medulloblastoma starts in the lower back part of the brain and tends to spread through the spinal fluid. These tumours are less common in adults, but they do occur.
Ø Germ cell tumours. Germ cell tumours may develop during childhood where the testicles or ovaries will form. But sometimes germ cell tumours affect other parts of the body, such as the brain.
Ø Craniopharyngiomas. These rare, noncancerous tumours start near the brain's pituitary gland, which secretes hormones that control many body functions. As the craniopharyngioma slowly grows, it can affect the pituitary gland and other structures near the brain.
