Medulloblastoma is a type of brain tumor that primarily affects children. It develops in the cerebellum, the part of the brain responsible for coordination and balance. This tumor can cause symptoms like headaches, nausea, and problems with movement. Early diagnosis and treatment are crucial for improving outcomes. Treatment for medulloblastoma often includes surgery to remove the tumor, followed by radiation therapy and chemotherapy. These methods aim to eliminate cancer cells and reduce the risk of recurrence. Advances in research and treatment options have significantly improved survival rates for children diagnosed with this condition, making it a focus of ongoing medical studies.
