Medulloblastoma is a type of harmful brain tumor. It starts in the cerebellum, at the bottom and back of the brain.
The cerebellum is the center for balance, coordination, and movement. Over time, the tumor can cause problems with these functions. This tumor can also block the flow of cerebrospinal fluid (CSF). CSF surrounds and protects the brain and spinal cord. Blocked flow can cause a buildup of pressure in the brain.
Cancer is when cells in the body split without control or order. These cells go on to form a growth or tumor. The term cancer refers to harmful growths. These growths attack nearby tissues. They also spread throughout the brain or spinal cord. It's not clear exactly what causes these problems. It’s likely a mix of genes and the environment.
A medulloblastoma can happen at any age. But, it’s more common in children and males.
Symptoms may not be noticed at first. Over time, they will appear and worsen.
A medulloblastoma may cause:
Nausea or vomiting
Headaches, mainly in the morning
Lack of coordination in the upper part of the body
Vision problems such as double vision or inability to look up with the eyes
Changes in hunger
