What are the types of brain tumors?

Many: There are way too many types of brain tumors to list in 400 letters. In short, we grade brain tumors from grade 1 (benign) to grade 4 (cancer). The most common example of grade 1 tumors are pituitary tumors and meningiomas. The most common grade 4 tumor is glioblastoma (gbm).

Multiple: There are primary tumors: meningiomas, oligodendrogliomas, gliomas (potentially highly dangerous if transforms), neuroblastomas, hamartomas, colloid cysts, just to list a few. These vary in location and benignity. Secondary tumors are called metastases, and come from skin, lung, kidney, and other primary cancer sites. More information can be found at mayo clinic site.

Several: The most common types of brain tumors are actually from the spread of another cancer to the brain. After this the most common cerebral tumors are grade 4 tumors called glioblastoma or gbm. Of course there are other benign tumor that come from the coverings of the brain. Other tumors can come from the fluid cavities or pituitary gland and have varied degrees of aggressiveness.
