What is The Medulla?The medulla is a long stem-like structure of the brain that makes the lower part of the brain. It is a cone-shaped mass of neurons that play a role in performing various functions such as vomiting and sneezing.
What is Medulloblastoma of The Brain?Medulloblastoma is a cancer of the lower part of the brain called the medulla oblongata. It is a common childhood cancer that grows rapidly in nature and can spread to the local area. It also tends to metastasize (can spread to other parts of the brain and spinal cord) and can spread through the cerebrospinal fluid. Cerebrospinal fluid is a colorless, clear fluid found in the brain and spinal cord. Cerebrospinal fluid provides protection and nutrition to the brain and spinal cord. It also plays a role in waste disposal. The 5-year survival rate with treatment is higher among children than adults.
CausesCertain genetic mutations (faulty changes in the genes) are responsible for the development of medulloblastoma.
