What Is A Medulloblastoma?

Medulloblastoma is a fast-growing, high-grade tumor that starts in the region of the brain at the base of the skull. These tumors often spread to other parts of the brain and spinal cord as well.

What Are The Symptoms Of A Medulloblastoma?

The most common symptoms include:

  • Behavioral changes
  • Changes in appetite
  • Increased pressure on the brain in which headaches, nausea, vomiting, drowsiness, and coordination problems can occur
  • Unusual eye movements may also occur

If the tumor has spread to the spinal cord, symptoms may include:

  • Back pain
  • Trouble walking
  • Problems controlling bladder and bowel functions

What Causes A Medulloblastoma?

As with many tumors, the exact cause of medulloblastoma is unknown. Changes have been identified in genes that may play a role in the development of medulloblastoma. There are also a few rare, genetic health syndromes that are associated with increased risk for developing this tumor.

What Are The Treatments For Medulloblastoma?

The treatment options include:

  • Surgery: with a goal of removing as much of the tumor as possible
  • Reduced-dose radiation
  • Chemotherapy: involves the use of medications that stop the growth of the tumor and can be given orally or through an IV, so that it can travel throughout the body
