Brain tumor displaces and compresses normal brain tissue.

Types of Brain tumor

There are various types of brain tumors but common brain tumors are.

Causes of Brain tumor

Medical science does not know how to prevent primary tumors that start in the brain and what causes of brain tumors. There are some risks for the brain tumors.

Symptoms of Brain tumor

Symptoms are depending on the tumor’s type, size, and location in the brain.

Some specific symptoms are related to functional areas of the brain.

Frontal lobe- behavioral and emotional changes, impaired judgment, impaired sense of smell, memory loss, paralysis on one side of the body, reduced mental abilities, and vision loss.

Treatments

Different types of treatments are available for brain tumor.

Surgery

Surgery is the one type of the treatment for brain tumors that can be reached without causing major injury to vital parts of the brain. Brain tumor surgeon known as neurosurgeon performs a craniotomy to open the skull and remove the tumor.

Aim of brain surgery.

Radiation

Chemotherapy

Chemotherapy drugs works by disrupting the growth of cells division. It affects not only tumor cells but normal cells, thus causing side effects, especially in fast growing cells (e.g., hair, digestive, blood).

Drugs- carmustine (BCNU), lomustine (CCNU), and temozolomide (Temodar).
