Posterior Fossa Tumor

Treatments for Posterior Fossa Tumor

Posterior fossa tumors, whether they’re cancerous or not, are most often removed via surgery, as there is limited space in the posterior fossa region of the brain, so the tumor can press on some of the brain’s critical structures, including the brain stem and cerebellum, if it grows. However, complete removal of the tumor can sometimes be difficult because of the proximity to these brain structures, which need to be preserved. If a complete resection is not possible, the surgery is often followed with radiation therapy to kill the remaining cancer cells.
