Brain Cancer

A brain tumor is a cancerous or a non-cancerous growth of cells in the brain. This growth of abnormal cells can take place in any part of the brain or it can happen in any other body part and spread to the brain. Primary brain tumours are named after the brain tissue type from where cancer develops. Different names and types of brain cancers reflect the different cells in the brain that can become cancerous. Although benign or non-cancerous, tumours can affect the brain functioning, and the grade of cancer determines the severity.
A benign tumour does not invade the surrounding tissues or spread to other areas. It is the cancerous or malignant tumours that take the nutrients, blood, and space of the healthy cells, and can also spread to other parts of the body. Common brain tumours are gliomas, meningiomas, pituitary adenomas, vestibular schwannomas, and primitive neuroectodermal tumours (medulloblastomas).

Radiation Therapy For Brain Cancer

It uses high-energy beams, such as X-ray or proton beams to kill cancer cells. Radiation therapy is a nonsurgical procedure that delivers a single high dose of precisely targeted radiation. It can be applied to your entire brain. Whole-brain radiation is often used to treat cancer that has spread to the brain from some other part of the body.
