The brain tumour

are clasified as primary and secondary and these start at some parts of the body and the first affects brain and the other appears in brain. Brain tumours, which appear on the people who are under 9 years old and above 55 years old ,appear on white people and on men especially. The symptoms get difficult the diagnosis to treat appearing from time to time unusually. It is necessary to monitor the brain when the symptoms appear suspecting for the pressure to rise ,so the MRG and tomoghraphy is appealed. The brain tumours put pressure on the brain growing in the skull. They show symptoms depending on where they exist and the brain section which they put pressure on.They first show symptoms on the pressure inside the head like all other events inside the head.The tumour go on growing and put pressure on the brain in skull which doesnt have ability to grow.The brain loses its normal spectre and cannot fulfil its functions.The both side of the brain is created symetrically and the borders are orderly made up.Any formation which quashing this symetry can harm the brain and put pressure on the brain.There are two types of the brain tumours.
1.Nonmalignantl tumours:They can easily removed from the brain tissue and eliminated almost completely. So the results are positive.This results unfortunately may not be positive everywhere depending on the place of the tumour appearing critical sections of the brain. They can cause permanent effects and trouble at brain functions even they are not fatal although they increase slowly.
2.Malignant tumours:They are the mud form tumours increasing rapidly and hard ro remove by operation. They appear periodically in brain and go on putting pressure even if they are eliminated from the brain by operation.There is one type of this tumour causing the death of the patient in 5-6 months after operation while there is one type of it giving the chance for the patient to live 5 years
