what is medulloblastoma

Medulloblastoma is a type of brain cancer that starts in the cerebellum, which is the part of the brain responsible for muscle coordination, balance, and movement. It is the most common cancerous brain tumor in children, but it can also occur in adults. Medulloblastoma cells grow quickly and can spread to other parts of the brain through the cerebrospinal fluid. Symptoms of medulloblastoma include morning or nighttime headaches, nausea, vomiting, and difficulty with balance and coordination. To diagnose medulloblastoma, a medical history review, neurological exam, and imaging tests such as MRI are used. Treatment for medulloblastoma usually involves surgery to remove as much of the tumor as possible, followed by radiation and chemotherapy. The prognosis for medulloblastoma depends on factors such as the patients age, the extent of the tumor, and the presence of certain genetic mutations.
