How is brain cancer classified?

The current classification of brain cancer is based on the standards established by the World Health Organization in 1975, which divides brain cancer into eleven categories.

(1) Neuroepithelial tumors include astrocytomas, oligodendrogliomas, ependymal and choroid plexus tumors, pineal tumors, neural cell tumors (gangliocytomas, neuroblastomas), poorly differentiated tumors and embryonal tumors (glioblastoma multiforme, medulloblastoma), etc.

(2) Neurotheca tumors: including neurotheca tumors (Schwann cell tumors), neurofibromas, etc.

(3) Meningioma: including meningioma and meningeal sarcoma.

(4) Malignant lymphoma: mainly refers to primary malignant lymphoma.

(6) Cerebrovascular tumors: cavernous hemangioblastoma.

(7) Deformed scapula, carpal tunnel syndrome, epidermoid cyst, dermoid cyst.

(8) Vascular malformation: capillary dilation.

(9) Pituitary tumors: anterior pituitary tumors.

(10) Extension of tumors to local areas: such as carotid glomerulonephritis.

(11) Metastatic tumor: refers to a tumor that has metastasized from other organs in the body to the brain.
