    Study Notes

    • Cancerous brain or spinal cord tumors are rare, with less than 1% lifetime chance for adults in the U.S.
    • Around 25,000 adults receive this diagnosis yearly.
    • Most brain tumors are gliomas, developing in glial cells, which support and protect the brain.
    • Astrocytomas are a type of glioma that form in astrocytes, star-shaped glial cells.
    • Glioblastomas are aggressive astrocytomas.
    • Oligodendrogliomas are rare gliomas that originate in cells creating myelin, the protective covering for brain nerves.
    • Medulloblastomas, another type of cancerous brain tumor, grow quickly at the base of the skull and are common in children.
    • Brain tumors are graded on a scale from one to four, with one being slow and benign, and four being fast and malignant.
    • Benign and cancerous brain tumors share similar symptoms but treatments differ.
    • To determine if a tumor is cancerous, doctors may perform a tumor tissue biopsy, request imaging tests, or conduct a spinal tap.
    • Warning signs of brain tumors include worsening headaches, speech difficulties, weakness, or vision problems on one side of the body.
    • Seek medical attention immediately if experiencing these symptoms, as early diagnosis and treatment are crucial.
