Facts on Brain Tumor

Compiled by Gayathri | Medically Reviewed by The Medindia Medical Review Team on Jun 20, 2014

A brain tumor is a collection of damaged cells that multiply without control within the brain. It is also called as neoplasm, growth, mass or lesion and it is classified as either primary or secondary and can be benign or malignant.

Primary brain tumors generally develop in the brain and remain the same. Secondary brain tumors are cancers that develop anywhere in the body and spread to the brain. Malignant brain tumors grow rapidly and occupy other cells. Benign brain tumors generally do not grow rapidly but can be life threatening.
