Glioblastoma multiforme (GBM), also known as glioblastoma and grade IV astrocytoma, is the most common and most aggressive cancer that begins within the brain. Signs and symptoms are initially non specific. They may include headaches, personality changes, nausea, and symptoms similar to that of a stroke. Worsening of symptoms is often rapid. This can progress to unconsciousness.

The cause of most cases is unclear. Uncommon risk factors include genetic disorders such as neurofibromatosis and Li Fraumeni syndrome and previous radiation therapy. Glioblastomas represent 15% of brain tumors. They can either start from normal brain cells or develop from an already existing low-grade astrocytoma. The diagnosis is typically made by a combination of CT scan, MRI scan, and tissue biopsy.
