Hi! My sister has just been diagnosed with Medullablastoma, she had a total resection and clear spinal MRI but still waiting on a lumber puncture which we expect will be clear. I saw you shared about your daughter and that she opted for radiation only. We are currently considering treatment options but are concerned about the neurocognitive side effects of high dose radiation. I would love to hear about your daughters experience and the dosage of radiation. Some of our doctors have suggested low dose radiation and chemotherapy because of the risks of memory lose etc. Thanks!
