Type of disease: Rare conditions
Pineoblastoma is a cancerous (malignant) tumor that develops in the pineal gland. The pineal gland is located in the brain and makes the hormone melatonin to regulate the body’s sleep patterns. Pineoblastoma is a type of primitive neuroectodermal tumor (PNET). Pineoblastoma mainly affects children, but can also occur in adults. Treatment of pineoblastoma includes surgery to remove as much of the tumor as possible, followed by radiation therapy and chemotherapy.
