Brain Tumor Types

There are over 100 different tumor types recognized by the World Health Organization (WHO) Classification of Tumors of the Central Nervous System (CNS).

To diagnose brain and other CNS tumors, specialists consider the appearance of the tumor tissue under a microscope, how active the tumor tissue is, and its unique molecular features through biomarker testing. Knowing one’s diagnosis helps individuals living with brain tumors, their care partners, and their health care teams predict its behavior, identify available treatment options, and identify potential eligibility in clinical trials.

The following pages provide an overview of the most common brain tumor types. As every person and brain tumor is unique, it is important to speak with your health care team to understand your unique diagnosis.
