Meningioma constitute about one third of all primary brain tumors. Meningiomas - 90% are benign tumors that grow from brain membranes. They tend to grow slowly and inside. Meningioma often reaches a large enough size before it is diagnosed. Despite the fact that, as mentioned above, it is usually a benign tumor, however, it can be life-threatening because it can put pressure on the brain regions responsible for vital bodily functions. In 10% of cases of meningioma is malignant and can metastasize to other organs. Some patients may develop more than one meningioma.
The younger the patient at diagnosis, the better the long-term prognosis. For people who are being treated meningioma in Israel, 10-year relative survival rate is 81.4%. Recall that the 10-year survival rate - the percentage of people who are still alive 10 years after diagnosis
Why do patients choose to treat meningioma Israel and clinic Assuta?

In particular, for the treatment of pathologies of the brain, including those for the treatment of meningioma, Gamma Knife is used in Israel - the so-called system for stereotactic radiosurgery in which the radiation source is a radioactive cobalt-60.
Despite the name, this procedure does not involve a surgical incision of the brain. In addition, the "blades" gamma knife are actually focused beams of gamma radiation. To 192 radiation beams are very precisely focused on the affected area of the brain, so the healthy tissue surrounding the tumor is almost not damaged.

- Professor Moshe Adani - one of the leading experts in Israel that specializes in brain surgery. His experience in this area - for almost 40 years! On account of the surgeon - thousands of successful operations and patients cope with its help with brain diseases, including meningiomas.

The anomaly can arise as spontaneously as well be hereditary. A risk factor for spontaneous occurrence may be, for example, the previous irradiation of the head, there is also a link between hormonal status and human meningiomas.
Signs and symptoms of meningioma
The most common symptoms are headaches and weakness in the arm or leg. Some of the symptoms associated with the specific area of the brain in which there is a meningioma.
Other symptoms include:
