![]() ![]() Choroid plexus tumors can be benign or malignant. Choroid plexus tumors are located in the fluid-filled cavities in the brain, called the ventricles. This fluid is called cerebrospinal fluid. Choroid plexus tumors start in cells that make the fluid that surrounds the brain and spinal cord. Glioblastoma is the most common type of malignant brain tumor. Gliomas can be benign, but most are malignant. Types of gliomas and related brain tumors include astrocytoma, glioblastoma, oligodendroglioma and ependymoma. The glial cells surround and support nerve cells in the brain tissue. Gliomas are growths of cells that look like glial cells. The pressure on the nerve from the tumor may cause hearing loss and imbalance. These nerves are twined together to form the vestibulocochlear nerve (eighth cranial nerve). Malignant brain tumors tend to be fast-growing brain tumors.Īn acoustic neuroma (vestibular schwannoma) is a benign tumor that develops on the balance and hearing nerves leading from the inner ear to the brain. Some brain tumor types can be benign or malignant.īenign brain tumors tend to be slow-growing brain tumors. These types are called brain cancers or malignant brain tumors. Some types of brain tumors usually are cancerous. These are called noncancerous brain tumors or benign brain tumors. Some types of brain tumors usually aren't cancerous. Your health care team uses this information to figure out the type of brain tumor. Special lab tests on the tumor cells can give information about the cells. ![]() The type of brain tumor is based on the kind of cells that make up the tumor. Common treatments include surgery and radiation therapy. The brain tumor size could become quite large before the tumor is detected.īrain tumor treatment options depend on the type of brain tumor you have, as well as its size and location. ![]() If a brain tumor starts in a part of the brain that's less active, it might not cause symptoms right away. Some parts of the brain are less active than others. Other brain tumors grow very large before they're found. Some brain tumors are found when they are very small because they cause symptoms that you notice right away. The cancer cells can invade and destroy the brain tissue.īrain tumors range in size from very small to very large. Other brain tumors are brain cancers, also called malignant brain tumors. Noncancerous brain tumors may grow over time and press on the brain tissue. Many different types of primary brain tumors exist. These tumors are secondary brain tumors, also called metastatic brain tumors. Sometimes, cancer spreads to the brain from other parts of the body. ![]()
