A brain tumor happens when abnormal cells form inside the brain. There are two main types of tumors: malignant or cancerous tumors and benign tumors. Cancerous tumors can be broken up into main tumors that begin within the brain, along with secondary tumors that have spread from someplace else, called brain metastasis tumors. All types of brain tumors can produce symptoms which change based on the component of the brain involved. These indicators could include headaches, seizures, difficulty with eyesight, vomiting, and mental changes. The headache is classically worse in the morning and goes off with vomiting. More particular issues may include difficulty in walking, talking, and with feeling. As the disorder progresses unconsciousness might happen.

The cause of the majority of brain tumors is unknown. Uncommon risk factors include inherited neurofibromatosis, exposure to vinyl chloride, Epstein–Barr virus, and ionizing radiation. The signs for cell phones isn't apparent. The most frequent forms of primary tumors in adults are meningiomas (generally benign), and astrocytomaslike glioblastomas. In children, the most frequent form is a cancerous medulloblastoma. This is then frequently supported by a biopsy. Depending on the findings, the tumors are split into distinct levels of seriousness.

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

Types of brain tumor

Choroid plexus carcinoma
Craniopharyngioma
Embryonal tumors
Ependymoma
Medulloblastoma
Pineoblastoma

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:

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
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
Causes of brain tumor

Primary brain tumors originate in the brain itself or in cells near to it, like in the brain-covering membranes (meninges), cranial nerves, pituitary gland or pineal gland.

Primary brain tumors start when normal cells get mistakes (mutations) within their DNA. These mutations enable cells to grow and divide at elevated rates and to keep on alive when healthy cells will perish. The outcome is a mass of abnormal cells, which creates a tumor.

Primary brain tumors are not as frequent than are secondary brain tumors, where cancer starts elsewhere and spreads into the brain.

Each gets its title from the kind of cells included. Examples include:

PNETs. Primitive neuroectodermal tumors (PNETs) are rare, cancerous tumors that start in embryonic (fetal) cells in the brain. They can occur anywhere in the brain.
Germ cell tumors. Germ cell tumors may develop during childhood where the testicles or ovaries will form. But sometimes germ cell tumors move to other parts of the body, such as the brain.
Craniopharyngiomas. These rare, noncancerous tumors 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.
Acoustic neuromas (schwannomas). These are benign tumors that develop on the nerves that control balance and hearing leading from your inner ear to your brain.
Pituitary adenomas. These are mostly benign tumors that develop in the pituitary gland at the base of the brain. These tumors can affect the pituitary hormones with effects throughout the body.
