A brain tumor occurs when abnormal cells form within the brain. There are two main types of tumors: malignant (cancerous) tumors and benign (non-cancerous) tumors. These can be further classified as primary tumors, which start within the brain, and secondary tumors, which most commonly have spread from tumors located outside the brain, known as brain metastasis tumors. All types of brain tumors may produce symptoms that vary depending on the size of the tumor and the part of the brain that is involved. Where symptoms exist, they may include headaches, seizures, problems with vision, vomiting and mental changes. Other symptoms may include difficulty walking, speaking, with sensations, or unconsciousness.
A glioma is a type of primary tumor that starts in the glial cells of the brain or spinal cord. They are cancerous but some are extremely slow to develop. Gliomas comprise about 30 percent of all brain tumors and central nervous system tumours, and 80 percent of all malignant brain tumours.
Oligodendrogliomas are a type of glioma that are believed to originate from the oligodendrocytes of the brain or from a glial precursor cell. They occur primarily in adults but are also found in children.
The Richard Lounsbery Award is given to American and French scientists, 45 years or younger, in recognition of "extraordinary scientific achievement in biology and medicine."
A brainstem glioma is a cancerous glioma tumor in the brainstem. Around 75% are diagnosed in children and young adults under the age of twenty, but have been known to affect older adults as well. Brainstem gliomas start in the brain or spinal cord tissue and typically spread throughout the nervous system.

Diffuse midline glioma, H3 K27-altered (DMG) is a fatal tumour that arises in midline structures of the brain, most commonly the brainstem, thalamus and spinal cord. When located in the pons it is also known as diffuse intrinsic pontine glioma (DIPG).
Karl Alexander Deisseroth is an American scientist. He is the D.H. Chen Foundation Professor of Bioengineering and of psychiatry and behavioral sciences at Stanford University.
James Rutka is a Canadian neurosurgeon from Toronto, Canada. Rutka served as RS McLaughlin Professor and Chair of the Department of Surgery in the Faculty of Medicine at the University of Toronto from 2011 – 2022. He subspecializes in pediatric neurosurgery at The Hospital for Sick Children (SickKids), and is a Senior Scientist in the Research Institute at SickKids. His main clinical interests include the neurosurgical treatment of children with brain tumours and epilepsy. His research interests lie in the molecular biology of human brain tumours – specifically in the determination of the mechanisms by which brain tumours grow and invade. He is the Director of the Arthur and Sonia Labatt Brain Tumour Research Centre at SickKids, and Editor-in-Chief of the Journal of Neurosurgery.
Isabelle M. Germano is a neurosurgeon and professor of neurosurgery, neurology, and oncology at the Icahn School of Medicine at Mount Sinai Hospital.

Viviane Tabar is an American neurosurgeon, the Chair of the Department of Neurosurgery at Memorial Sloan Kettering Cancer Center in New York since 2017.
Clinica 0-19 is a medical clinic in Monterrey, Mexico that claims to treat diffuse intrinsic pontine glioma (DIPG). Although DIPG is currently regarded as one of the most devastating pediatric cancers, with a survival rate of <1% over five years, the clinic states that their treatment, which can cost hundreds of thousands of dollars, has resulted in some patients no longer having any evidence of disease. However, there is no credible evidence to support their claims and at least some of their patients were found to have tumor growth a few months later. Oncologists and others have criticized the clinic's lead doctors, Alberto Siller and Alberto Garcia, for their lack of transparency, for not publishing their treatment protocol or survival rates, for the high costs of treatment, and for discouraging their patients from using radiation therapy.
