Meningiomas: Causes, Symptoms, and Treatment
Causes of Meningiomas
Meningiomas are usually caused by a mutation in the NF2 gene, which codes for a protein that suppresses tumor growth. This mutation can be inherited or acquired.
Symptoms of Meningiomas
The symptoms of meningiomas can vary depending on the size and location of the tumor. Common symptoms include:
- Headaches
- Seizures
- Weakness
- Numbness
- Difficulty with speech or language
- Vision problems
Treatment Options
The treatment for meningiomas depends on the size and location of the tumor. Treatment options include surgery, radiation therapy, and chemotherapy.
Surgery is the most common treatment for meningiomas. The goal of surgery is to remove the tumor completely. However, this is not always possible, especially if the tumor is located near critical structures in the brain.
Radiation therapy is used to kill tumor cells. Radiation therapy can be used before or after surgery.
Chemotherapy is used to kill tumor cells that have spread to other parts of the body.
