BRAIN TUMORS (Meningioma and Oligodendroglioma) I. Pathology A. Meningioma II. EtiologyA. No known cause. Uncontrolled division of meningeal cells III.
SpecificsA. Affected cell – meninges (cover and protection of brain and spinal cord) B. Accounts for 20% of all intracranial tumors. Typically benign.
Between skull and brain. Compresses but does not invade brain IV. Symptoms/SignsA. HeadachesB. Stroke-like symptoms. Seizures D.
Loss of vision. Personality changes. CT scans and MRI’s can determine presence and exact location. TypesA. Convexity (curved part of the skull) B.
Cavernous sinus C. Sphenoid wind. Clavus and regions. Cerebellar (also occur) VI. Treatments A. Surgical removal (most common, first option) B.
Regular radiation. Stereotactic Radiosurgery (precise radiation delivered to the brain without harm to surrounding tissue/ this is used for that are more difficult to safely remove) VII. PrognosisA. Excellent (more than 95% survival rate) B.
Minimal physical therapy may be necessary My aunt just recently had surgery to remove a benign. The surgery was a success and had she survived despite further complications, her treatment following the surgery was to be mere physical therapy to regain full or partial use of her left hand. I. Pathology A. OligodendrogliomaII.
EtiologyA. Unknown III. SpecificsA. Affects (responsible for myelin production, which covers nerves and allows for quick conduction of information) B. Most common in male adults. May be benign or malignant and spread to other parts of brain or even outside IV.
The Essay on Brain Cancer Tumor Tumors Cells

They have distinct ... are treated with a combination of chemotherapy, radiation therapy, and surgery. A new procedure is being tried called gamma knife, which ... is a type of radio surgery. It uses precise radiation to isolate and kill the tumor. ...
Symptoms/SignsA. HeadachesB. Vomiting C. Visual complications.
Memory loss. Problems with coordination and speech. Mood and personality changes. Paralysis on one side.
CT scans and MRI’s can determine presence and exact location of tumors. TypesA. Frontal lobe B. Temporal lobe VI. Treatment. Surgery.
Radiotherapy C. Chemotherapy VII. PrognosisA. Poor long terms. Often fatality In addition to current treatment methods for tumors (chemotherapy, radiation, surgery, and stereo static radiosurgery), testing is being done to determine the effects of hyperthermia, gene and viral therapy, as well as immunotherapy (vaccines) as possible treatment methods.
This may be useful because most tumors are more sensitive to heat than other tissues. Of course, as with all cancers and diseases, continuous research is also being done to determine specific causes. Bibliography 1. ) “Histochemistry and Cell Biology.” Springer Berlin Heidelberg.
