Today i DR Muhammad Shakeel awaisi going to tell you about the brain tumor. Brain tumor has also some types as per i am aslo a doctor i am giving the information about brain tumor.

What is a brain tumor?

A brain tumor is a collection, or mass, of abnormal cells in your brain. Your skull, which encloses your brain, is very rigid. Any growth inside such a restricted space can cause problems. Brain tumors can be cancerous (malignant) or noncancerous (benign). When benign or malignant tumors grow, they can cause the pressure inside your skull to increase. This can cause brain damage, and it can be life-threatening.

Brain tumors are categorized as primary or secondary. A primary brain tumor originates in your brain. Many primary brain tumors are benign. A secondary brain tumor, also known as a metastatic brain tumor, occurs when cancer cells spread to your brain from another organ, such as your lung or breast.

Overview

A brain tumor is a mass or growth of abnormal cells in your brain.

Many different types of brain tumors exist. Some brain tumors are noncancerous (benign), and some brain tumors are cancerous (malignant). Brain tumors can begin in your brain (primary brain tumors), or cancer can begin in other parts of your body and spread to your brain (secondary, or metastatic, brain tumors).

How quickly a brain tumor grows can vary greatly. The growth rate as well as location of a brain tumor determines how it will affect the function of your nervous system.

Brain tumor treatment options depend on the type of brain tumor you have, as well as its size and location.

Symptoms

The signs and symptoms of a brain tumor vary greatly and depend on the brain tumor's size, location and rate of growth.

General signs and symptoms caused by brain tumors 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 behavior changes

Seizures, especially in someone who doesn't have a history of seizures

Hearing problems

Types

Acoustic neuroma

Astrocytoma

Brain metastases

Choroid plexus carcinoma

Craniopharyngioma

Embryonal tumors

Ependymoma

Glioblastoma

Glioma

Medulloblastoma

Meningioma

Oligodendroglioma

Pediatric brain tumors

Pineoblastoma

Pituitary tumors

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.

Secondary brain tumors

Secondary brain tumors make up the majority of brain cancers. They start in one part of the body and spread, or metastasize, to the brain. The following can metastasize to the brain:

lung cancer

breast cancer

kidney cancer

skin cancer

Secondary brain tumors are always malignant. Benign tumors don’t spread from one part of your body to another.
