Do primary brain tumors cause headaches?
There are two types of primary brain tumor: extra- and intraaxial brain tumors. Extraaxial brain tumors develop around the brain mostly from the meninges and the bone. Intraaxial primary brain tumors develop from the brain parenchyma, in which glioma is the most common type. Both types of primary brain can cause headache either through the local traction of pain-sensitive structures surrounding the tumor or global traction from increased intracranial pressure.
