Cerebral Hemisphere Tumors

Cerebral hemisphere tumors are abnormal growths that develop in the brain’s cerebral hemispheres, which are the two large halves of the brain that control movement, thinking, and emotions. These tumors can vary in size, location, and type, and they can cause a range of symptoms depending on their characteristics.

Types of Cerebral Hemisphere Tumors:

1. Gliomas: These tumors originate from the supportive cells of the brain and can include astrocytomas, oligodendrogliomas, and ependymomas.
2. Meningiomas: Arising from the meninges, the protective layers surrounding the brain and spinal cord.
3. Metastatic Tumors: Cancerous cells that have spread to the brain from other parts of the body, such as the lungs or breasts.
4. Pituitary Tumors: Abnormal growths that develop in the pituitary gland, which is located at the base of the brain.
5. Medulloblastomas: A type of tumor that typically occurs in children and originates in the lower part of the brain.
6. Hemangioblastomas: Rare tumors that develop in the blood vessels of the brain.

Causes of Cerebral Hemisphere Tumors:

1. Genetic Factors: Inherited genetic mutations can increase the risk of developing certain types of brain tumors.
2. Exposure to Radiation: Previous radiation therapy to the head or neck can elevate the risk of developing brain tumors later in life.

6. Lumbar Puncture (Spinal Tap): Collects cerebrospinal fluid for analysis, which can help diagnose certain types of brain tumors or infections.
7. Functional MRI (fMRI): Evaluates brain function by measuring blood flow changes in response to specific tasks or stimuli.
8. Positron Emission Tomography (PET) Scan: Uses a radioactive tracer to detect metabolic activity in the brain, which can help differentiate between tumor types.
9. Angiogram: Provides detailed images of the blood vessels in the brain and can help identify abnormalities or blood flow patterns associated with tumors.
10. Genetic Testing: To identify specific genetic mutations or markers associated with an increased risk of developing brain tumors.

Treatments for Cerebral Hemisphere Tumors:

1. Surgery: The primary treatment for many cerebral hemisphere tumors involves surgical removal of the tumor tissue.
2. Radiation Therapy: Uses high-energy beams to target and destroy cancer cells, either as a standalone treatment or in combination with surgery or chemotherapy.
3. Chemotherapy: Administering drugs that kill cancer cells or inhibit their growth, either orally or intravenously.
4. Targeted Therapy: Uses drugs or other substances to specifically target cancer cells while minimizing damage to healthy cells.
5. Immunotherapy: Stimulates the body’s immune system to recognize and attack cancer cells.
6. Corticosteroids: Medications that reduce swelling and inflammation in the brain, helping to alleviate symptoms such as headaches and edema.
7. Antiepileptic Drugs: Medications that help control seizures associated with brain tumors.
8. Anti-nausea Medications: Prescribed to alleviate nausea and vomiting often associated with brain tumors or their treatments.
9. Palliative Care: Focuses on improving quality of life and relieving symptoms, particularly in cases where the tumor cannot be completely removed or cured.
