 What is brain tumor? 

Brain tumor is a mass or growth of abnormal cells in the brain or skull. There are many types of brain tumors, such as meningiomas (tumors that form on membranes that cover the brain and spinal cord). Brain tumors can be benign, or malignant. The outcome of the prognosis depends on the pathological diagnosis. The type and location of a brain tumor could be substantially different between pediatric and adult. A primary brain tumor originates in your cranial nerve tissue, and a secondary brain tumor, also known as a metastatic brain tumor, occurs when cancer cells spread to your brain from another organ. The incidence rate of brain tumor is about 28 in 100,000 and it is regarded to be a rare cancer.
