Symptoms and Causes of Medulloblastoma

Medulloblastoma presents differently from patient-to-patient. Your child may experience all, some, or even none of the following symptoms

  • Headaches (especially in the morning)
  • Morning nausea and vomiting
  • Fatigue
  • Difficulty walking and/or balance problems
  • Tilting the head to one side
  • Problems with vision or an eye turning inwards
  • Problems with motor skills that worsen over time

If the tumor spreads to the spinal cord the patient may also experience:

  • Back pain
  • Difficulty walking
  • Inability to control bladder and bowel functions

Causes of Medulloblastoma

Researchers do not yet know what causes Medulloblastoma, however there is a small amount of medulloblastomas that have been traced to genetic markers. Like most cancers, Medulloblastoma occurs when something goes wrong with the process of cell reproduction.

Understanding What Cancer Is

Cells use DNA, the building blocks of genes, in order to carry out various functions, including making more cells. Sometimes pieces of DNA become damaged or are copied incorrectly. Scientists call this a mutation. Usually, cells with mutations in their DNA either repair the mutation or die (a process called apoptosis). Sometimes, though, cells with mutations can’t be repaired and don’t die like they are supposed to. In certain cases, these mutated cells begin to divide quickly, which may cause a person to develop cancer.
