Medulloblastoma is a type of brain tumour that is considered cancerous or malignant. It originates in the cerebellum, the part of your brain that controls balance and coordination. Medulloblastomas are more common in children but can also occur in adults. The symptoms you might experience can include headaches, nausea, vomiting, difficulties with balance and coordination, and changes in your ability to think and process information. The exact cause of medulloblastoma is unknown, but it involves mutations in the DNA of brain cells that cause them to grow uncontrollably. Treatment usually involves a combination of surgery to remove as much of the tumour as possible, followed by radiation therapy and possibly chemotherapy to kill any remaining cancer cells. The approach to treatment and your prognosis, or outlook, depends on various factors, including the size and location of the tumour, whether it has spread, and your overall health.
