BRAIN TUMOR

INTRODUCTION TO BRAIN:-

The brain is a soft, spongy mass of tissue.It is the main controlling organ of human body.As the brain is very delicate and sensitive part of body so it is protected by the bones of the skull and is present in protective cranium also called brain case and other three thin membranes known as meninges. Watery fluid called cerebrospinal fluid cushions the brain. This fluid flows through spaces between the meninges and through spaces within the brain called ventricles.

PARTS OF BRAIN:-
The brain has three parts.
(1)Fore Brain
(2)Hind Brain
(3)Mid Brain

The brain tumor disease is a kind of an abnormal(not normal) growth of cells within the most delicated part of the human body "The brain".This can be cancerous as well as non-cancerous.

It is defined or said as any intracranial(the whole brain) tumor which is been created by abnormal(un normal) and uncontrolled unhandled cell division(reproduction of cells), normally which is in the humans brain.Neurons, glial cells (astrocytes, oligodendrocytes, ependymal cells), lymphatic tissue, blood vessels), or in the cranial nerves or myelin-producing Schwann cells, in the brain which envelopes (meninges), skull.

Commonly,Primary brain tumors are commonly located ,present in the back side or posterior cranial side in the children and in the anterior two-thirds(2/3) is of the cerebral hemispheres in adults, eventhough they can affect any part of the human brain.

SYMPTOMS OF TUMOR:-
Symptoms of brain tumors may base on of the two factors that are
(1)tumor size or its volume or space occupying brain
(2)tumor location(where the tumor is present)

In small children which are under the age of 2 years, mostly near about 70% of brain tumors are medulloblastoma, ependymoma, and low-grade glioma.These tumors in the small childen under the age of 2years are dangerous for these small childrens.
