Meningioma is the most common type of tumour that arises from meninges (a three-layered membrane that covers the brain and spinal cord). In general, meningioma occurs in the brain, which can also grow on different sections of the spinal cord.
About 90% of meningiomas are categorised as benign tumours and remaining 10% are malignant tumours. Benign tumours are non-cancerous and do not spread in the body. However, a benign tumour can cause disability which can be life-threatening. Malignant tumours are cancerous and multiply uncontrollably and spread different parts of the body to invade surrounding tissue. Meningioma occurs most frequently in women, between the age of 40-70 years. The rate of growth of a tumour is uncertain.
In some cases of meningioma, several tumours grow simultaneously in different sites of the brain and spinal cord. This condition is known as multiple meningiomas.
SIGNS AND SYMPTOMS
Signs and symptoms mainly depend on the location of the tumour in the brain and spinal cord. The following are the symptoms of meningioma:

The treatment depends on factors such as age, medical history, size and location of tumour. The following are the treatment options for meningioma:
Surgical technique- It is done by following a procedure called craniotomy which involves the removal of tumour by making a hole through the skull. This surgery may be time consuming depending on size and location of the meningioma.
Radiation therapy involves the use of high-energy x-rays or other particles to destroy the DNA of the abnormal cells. Tumour shrinks after radiation therapy, which helps reduce pressure on the brain or spinal cord. Radiation therapy is preferred after surgery to destroy the remaining abnormal cells.
Chemotherapy is the use of drug to destroy tumour cells and is generally unified with radiation therapy after surgery to treat advanced tumours. Chemotherapy treatment is applied, when chances of tumour reoccurrence are more.
Other drug medication provides relief from treatment side effects, but does not treat meningiomas. Alternative medicine therapy includes music therapy, meditation, relaxation exercises.
