OLIGODENDROGLIOMA MEDULLOBLASTOMA
Medulloblastoma and Oligodendroglioma is primary tumor of the central nervous system (CNS). This indicates that it begins in the brain or spinal cord. If possible, a part of tumor tissue will be removed during surgery to obtain an accurate diagnosis.

CAUSES OF OLIGODENDROGLIOMA AND MEDULLOBLASTOMAS
Cancer is a genetic disorder, which means that it is caused by changes in genes that control how our cells function. In many types of cancer, genes can be mutated (changed), causing cancer cells to grow and spread. The cause of the majority of medulloblastomas is unknown. A small percentage of childhood medulloblastomas are caused by gene changes that are passed down through families. There is no known cause of medulloblastomas in adults.
