Question

what is brain tumor and it's type?..​

Answer 1

Uncontrolled and abnormal cell growth in the brain is called a brain tumour. The space in our skull is restricted. Therefore, this extra growth inside our brain causes more pressure inside the skull, causing life-threatening complications, and also damaging our brain.

Tumours can be either benign or malignant. The benign ones are not cancerous and cannot spread to other parts of the brain or body. The malignant ones are cancerous, grow uncontrollably and can spread to other parts of the body.

Answer 2

Brain tumor is the cancer that affect the brain. It is a cancer that is originated in brain or else spread to the brain from other cancerous body. Tumor is formation of mass of cancerous cells due to abnormal cell division.The types of brain tumors are

1. Primary brain tumors

Primary brain tumors originate in your brain. They can develop from your:

• brain cells
• the membranes that surround your brain, which are called meninges
• nerve cells
• glands

Primary tumors can be benign or cancerous. In adults, the most common types of brain tumors are gliomas and meningiomas.

2) Gliomas

Gliomas are tumors that develop from glial cells. These cells normally:

• support the structure of your central nervous system
• provide nutrition to your central nervous system
• clean cellular waste
• break down dead neurons

Gliomas can develop from different types of glial cells.

The types of tumors that begin in glial cells are:

1. astrocytic tumors such as astrocytomas, which originate in the cerebrum
2. oligodendroglial tumors, which are often found in the frontal temporal lobes
3. glioblastomas, which originate in the supportive brain tissue and are the most aggressive type
