There are two main categories of brain tumors. Primary brain tumors are tumors that actually grow from the brain tissue itself. Gliomas are the most common type of brain tumor that a person can have. These tumors grow out of the glial tissues of the brain. A gliomas tumor can take on four forms. These forms are astrocytomas, ependymomas, brain stem gliomas and oligodendrogliomas. Each one of these four common gliomas tumors each grow out of a different type of glial tissue in the brain.
For instance, ependymomas will grow in the ventricles. This type is more common among children. Astrocytomas grow in the astrocytes of the brain. This type can grow anywhere astrocytes are located, including the spinal cord. Where the tumor forms will usually depend on the age of the patient. It is most common for one of these tumors to form in the cerebrum of an adult and the brain stem of a child.
Non-Gliomas Primary Brain Tumors
Other primary brain tumors exist that do not require glial tissue to form. Some of these include meningiomas, germ cell tumors and Schwannomas. Schwannomas are benign and form in the cells of the brain known as the Schwann cells. Women have a much higher chance of developing Schwanomas.
Meningiomas will grow out of the meningines in the brain. This is another benign form of brain tumor, yet some rare cases are not benign. Meningiomas grow very slowly. In fact, they grow so slowly that the brain has time to adjust to their presence, reducing the health risk of the tumor. They often need to grow much larger than other tumors before any noticeable symptoms occur. Middle aged women are at the highest risk of developing meningiomas.
Secondary Brain Tumors
The third major form of brain tumor is the secondary brain tumor. Secondary tumors do not grow out of brain tissue. In fact, secondary tumors grow in a completely separate part of the body. Through the unfortunate process of metastasis, these foreign tumors will often spread to the brain at a later date. Cells from other body parts will remain the same even after spreading to the brain. A secondary tumor can take the form of abnormal lung cells in the brain. This would happen if lung cancer spread to the brain through metastasis. Treatment of a secondary brain tumor must begin at the original source. For example, if lung cancer spreads to the brain it must be attacked at the lungs. The second step may then be to treat the areas where the tumor has spread, such as the brain. The process of brain surgery is very serious. Consult a brain surgeon if you have any questions or concerns about brain tumors.
