Brain Tumors And Brain Metastases
In the brain, a whole range of different tumors can arise.Some of them are benign, for example neurinoma. Normally, the benign tumors donot grow into the adjacent, healthy tissue. However, they can still lead toserious disorders and symptoms.
Cerebrum, cerebellum, brainstem and pituitary gland

Other brain tumors are malignant and destroy the surrounding brain tissue. These include the gliomas, they are a common type of brain tumor.
Brain Tumors risk factors
Brain tumors usually arise spontaneously, without any external cause or influence. One risk factor is ionizing radiation (radiation from previous radiotherapy or after nuclear accidents), which can be a cause of brain tumors. Only in very rare cases is a hereditary disease, which may favor the development of brain tumors.
Brain Tumors symptoms
Brain tumors can trigger many different symptoms. The symptoms that occur depend essentially on the type of tumor and its location in the brain. Common symptoms of brain tumors include vomiting, blurred vision, epileptic seizures, paralysis, speech disorders, headaches, and behavioral and personality changes.
Brain Tumors diagnosis
For diagnosis, the brain structures are depicted, for example with computer or magnetic resonance tomography.
Brain Tumors therapy
In brain tumors, surgery is usually the first step and is the basis for diagnosis and therapy. Often an operation alone is not enough and in addition, for example, chemo and / or radiation are performed.
Much more common than the actual brain tumors are brain metastases, ie offshoots of other originating tumors in the body. In many cases, brain metastases are caused by lung, breast or black skin cancer.
